* [libcpu][risc-v] Refactor the RISC-V architecture port
Introduce an opt-in unified RISC-V common layer for RV32 and RV64 while keeping existing BSPs on the legacy implementation during migration.
- use ARCH_RISCV and ARCH_CPU_64BIT for architecture and XLEN selection
- unify context, trap, MMU, cache, timer, SBI, SMP and ISA handling
- add PLIC, CLIC, ACLINT, APLIC and IMSIC support
- map physical hart IDs to contiguous logical CPU IDs
- add T-Head vendor overrides while preserving legacy ports
- migrate qemu-virt64-riscv with RV32 and RV64 support
- update clock_time, MM, LWP, OFW, PCI and Rust integration
Existing BSPs continue using legacy_common or common64 unless they select RT_USING_RISCV_NEW_COMMON.

* [libcpu][risc-v] skip disabled CPU nodes in early FDT walk
Rbb666 noted that rt_hw_fdt_install_early() walked every /cpus child
without checking status, so disabled cores still joined hart registration
and MMU capability probing. Skip nodes that are not okay/ok via
rt_fdt_device_is_available() before reading reg or mmu-type.

* [libcpu][risc-v] Fix per-CPU page table mapping
- reuse existing non-leaf page table entries when mapping per-CPU areas
- reject leaf entry conflicts instead of overwriting mappings

Add the ARM NVIC PIC driver, no-MMU I/O mapping, built-in FDT support, and Cortex-M CPU hooks required by the native RT-Thread device model.
|
|
Fixup fdt address reg and cells parse.
Support only option name way for earlycon.
Find the console device when using "stdout-path".
|
|
Fix garble caused by empty implementation of earlycon series
function in driver.If driver doesn't offer earlycon_id or rt_f
dt_earlycon_id.setup function but open option, the checking
of best_earlycon_id will failed.

The `rt_fdt_scan_chosen_stdout` will init fdt_earlycon data
without `msg` only, the `msg_idx` should not clean, too.
Because we check if have old messages by `msg_idx`

2.Fixup `rt_fdt_translate_address` cells value reader.

Maybe use for memory/DMA buffer init before
ofw_node unflatten.

We support OFW API to replace fdt old API, and add
IRQ, IO, Platform-Bus, CPUs ... OFW node contorl.
To support work with Device Tree or ACPI in drivers
that use IRQ, we make a programmable interrupt
controller driver's model.
