Based on the patch "bsp: cvitek: use rttpkgtool
to replace cvitek_bootloader", continue cleanup useless files.
Signed-off-by: Chen Wang <[email protected]>

Originally, for riscv big and little cores under bsp/cvitek,
after generating rtthread.bin, the cvitek_bootloader tool
would be used to package it and generate fip.bin and boot.sd
files that can be burned into sdcard. However, the
cvitek_bootloader tool repository is relatively large, and
it compiles and generates firmware such as fsbl, opensbi and
uboot from the source code level. And when using it, it
needs to be downloaded to the bsp/cvitek directory, which
will introduce pollution to source files in the RTT repository
under the original working path.
The new solution uses rttpkgtool, which is similar to
cvitek_bootloader, but it uses prebuilt firmware, so it is
very small and does not introduce pollution to the source file.

build warning: passing argument 1 of 'inv_icache_range' makes integer
from pointer without a cast [-Wint-conversion]
Analyze: The passed parameter type is void*, which is a pointer type,
but the required type is uintptr_t, which is an integer type. Therefore,
there will be a 'makes integer from pointer without a cast' warning.
Solution: casting the void* pointer to uintptr_t, ensure that the
function receives the correct type.

For bsp/cvitek, duo256m, the operation process is
slightly different when building images for riscv
and arm64.
To improve the user experience, unify the building
process and steps of the two as follows:
- Enter c906_little and execute `scons`
- Enter cv18xx_riscv/cv18xx_aarch64 and execute `scons`
That's all. Finally, we can get `fip.bin` and
`boot.sd` under `bsp/cvitek/output/milkv-duo256m`.
Update the README.md accordingly.

Duo's CPU combination is more complicated:
| BSP | B/L core| ISA | UART |
| ------------- | ------- |---------------- |-------|
| cv18xx_risc-v | Big | RISC-V C906 | UART0 |
| c906-little | Littel | RISC-V C906 | UART1 |
| cv18xx_aarch64| Big | ARM Cortex A53 | UART0 |
Printing ISA and big and small core information
during the boot process helps developers/testers
determine the CPU and serial port corresponding to
the current console.
In addition, the RTT logo printing has already
distinguished whether it is smart, so the bsp
printing no longer distinguishes.
Updated README to sync with this change.

By default, the small core enables D-Cache without ensuring cache
coherence. Therefore, when using shared memory, inconsistencies can
occur in the data read by the small core and the big core.
Solution: Migrate cache-related functions from the official
duo-buildroot-sdk library to implement cache-related operations in
rthw.h. This allows you to either disable D-Cache or call the
flush_dcache_range function before reading and after writing for
synchronization.
It is recommended to use the flush_dcache_range function, as disabling
D-Cache can have a significant performance impact.

description: In the bsp/cvitek/c906_little/board/interrupt.c, There is an issue with
setting the PLIC_PRIORITY[n].
analysis: PLIC_PRIORITY[n] each register corresponds to the priority of
a hardware interrupt number.
Solution: Each register is 4 bytes.
Multiply the total number of IRQs by 4 instead of dividing by 4.

RISCV_S_MODE configuration only affects the code in
libcpu/risc-v/virt64, and the only bsp using this
libcpu is qemu-virt64-riscv.
Considering s-mode is the default mode RT-Thread
running on virt64 machine, it seems unnecessary to
make RISCV_S_MODE a Kconfig option.
Solution: Remove RISCV_S_MODE from Kconfig and define
it as a macro in the code in libcpu/risc-v/virt64.
Plus, due to this macro is only related to virt64, rename
RISCV_S_MODE to RISCV_VIRT64_S_MODE.
Update the .config/rtconfig.h in this patch.

Confirmed with milkv, only the sd card version is sold
by default for duo in the market. The spi pins are
provided through stamp holes, so that users can solder
the corresponding components on their baseboard during
secondary development.
In order to simplify maintenance work, the mainline
will only support the sd-card version and no longer
support spinor/spinand.
Updated config files the same in this patch.

This patch introduces a remount feature for the DFS, allowing for the
modification of mount parameters without unmounting the filesystem,
the remount functionality helps modify certain mount flags (like `MS_RDONLY`) without
requiring an unmount, providing more control over mounted filesystems in the system.
The updates is essential for user space init proc to cleanup the runtime
resource, ensuring clean handling of cached data and enhancing system
robustness during power down processing.
Changes:
- Defined new constants for remount flags in `dfs_fs.h`.
- Added the `dfs_remount()` function in `dfs_fs.c` to handle remount operations.
- Introduced a check for unsupported flags and handle error conditions such as invalid paths
or non-directory targets.
- Updated the `dfs_mnt` structure in `dfs_mnt.h` to include a read-only flag (`MNT_RDONLY`).
- The `dfs_remount()` function allows changing the read-only status of a mounted filesystem.
- Added `MNT_LAZY_UMNT` and `MNT_RDONLY` flags to `dfs_mnt` structure.
- Introduced `dfs_mnt_setflags` function for dynamic flag management.
- Updated `dfs_remount` to utilize `dfs_mnt_setflags` for flag setting.
- Enhanced unmount operations with `dfs_mnt_umount_iter` and lazy unmounting.
- Added `dfs_pcache_clean` to handle cache cleanup for read-only mounts.
- Improved error reporting in `dfs_umount` for better user feedback.
- Refactored `sys_mount` to streamline parameter handling and support remounts.
- Introduced `_cp_from_usr_string` helper for user-space string operations.
- Updated internal APIs to ensure consistency in reference count management.

The patch introduces support for system reboot functionality and process teardown,
allowing for a clean shutdown and unmounting of the root filesystem. This is
necessary for ensuring a proper system shutdown process, especially when dealing
with resource cleanup and ensuring that all processes have exited before system
shutdown.
Changes:
- Added `lwp_teardown()` function to handle process cleanup and system teardown.
- Introduced `lwp_pid_wait_for_empty()` to wait for process ID table emptiness
before proceeding with shutdown.
- Updated `dfs_mnt_unref()` to trigger callbacks when unmounting a filesystem.
- Added new reboot types (`RB_AUTOBOOT`, `RB_POWER_OFF`) and implemented their
corresponding actions, including cleanup of processes and unmounting root
filesystem.
- Extended `sys_reboot()` to handle reboot and power off types with appropriate
callbacks for process and filesystem teardown.
- Introduced callback mechanism for root filesystem unmount notifications.

This change introduces the `lwp_runtime.c` component, which provides the
necessary runtime environment for the init process, including boot scripts,
shutdown, and poweroff functionalities. The initialization logic has been
moved from `lwp.c` to this new file, enhancing modularity and flexibility
in handling LWP runtime tasks.
Changes:
- Moved the `lwp_startup` function from `lwp.c` to `lwp_runtime.c` to handle
system initialization and runtime environment setup.
- Added `lwp_teardown` placeholder for system shutdown and cleanup tasks in
the future (though not yet implemented).
- Introduced the `LWP_USING_RUNTIME` configuration option in `Kconfig` to
conditionally enable the runtime environment.
- Updated the `SConscript` to conditionally include `lwp_runtime.c` based on
the `LWP_USING_RUNTIME` configuration.
- Removed the old `lwp_startup` code from `lwp.c`, simplifying the file.

This change introduces the `lwp_signal_kill_all` function, which allows a
signal to be sent to all processes in the system. The function iterates
over all PIDs and sends the specified signal to each process, except those
that are protected from signals. This enhancement provides a convenient way
to broadcast signals across all processes in the system.
Changes:
- Added `lwp_signal_kill_all` function in `lwp_signal.c` to broadcast a
signal to all processes by iterating over all PIDs using the existing
`lwp_pid_for_each` function.
- Introduced a new `kill_all_param` structure to encapsulate the signal
information needed for killing processes.
- Added internal `_kill_each` helper function for sending the signal to each
PID.
- Updated `lwp_signal.h` with the new function prototype for `lwp_signal_kill_all`.
- Modified `sys_kill` in `lwp_syscall.c` to call `lwp_signal_kill_all` when
a process is not specified.

This change introduces the `lwp_pid_for_each` function, which provides a
convenient and thread-safe method for iterating over PIDs with a user-
defined callback. This addition is necessary to support cases where
operations must be performed on each PID in the balanced tree, enhancing
flexibility and modularity for PID management.
Changes:
- Added `lwp_pid_for_each` function in `lwp_pid.c` to allow iteration
over PIDs using a callback function and optional data parameter.
- Defined a new internal `pid_foreach_param` structure to encapsulate
the callback and data for the iteration.
- Added `_before_cb` helper function for executing the callback on each
PID node during AVL traversal.
- Ensured thread safety by acquiring and releasing the PID lock around
the AVL traversal within `lwp_pid_for_each`.
- Updated `lwp_pid.h` with the `lwp_pid_for_each` function prototype and
included `rtthread.h` for necessary types.
