The boot EL will save in x0, when current EL is EL3,
kernel will jump to the EL2 after EL3.
But the x0 value is **3**, The init for EL2 will not work.
To fix it: the EL3 should jump to the EL2 init branch with not check,
and when SoC boot in EL2, kernel will jump to the EL2 test branch.

1. Configure the kernel default vaddr by RAM and TEXT offset.
2. Check the p_addr 2M align when set the stride in `rt_hw_mmu_map`.

libcpu/risc-v/common64/mmu.c uses the external
symbol "__bss_end" (this symbol generally is
defined in the link script file) and depends
on the extern declaration of this symbol in
the bsp's "board.h". This is not a problem in
implementation, but it is not a good habit.
If this extern symbol is used locally, just
declare it locally should be better.
In this way, there will be no dependency of
the kernel core on the bsp header file. And
there will be no special requirements for the
bsp board code, such as the need to make
extern declarations for these "__bss_end"
symbols in "board.h".
This patch currently only explicitly externly
declares "__bss_end" inside libcpu itself.
The code of "#include <board.h>" is kept, because
the modification involved is too large, it is
necessary to clean up the bsp involved before
cleaning this include code line uniformly.

* libcpu: cleanup undefined rt_hw_mmu_kernel_map_init
rt_hw_mmu_kernel_map_init() is declared in header files but
no definition found, cleanup the code.

* bsp: allwinner: d1: remove calling of rt_hw_mmu_kernel_map_init
rt_hw_mmu_kernel_map_init is an undefined function, calling it
is meaningless.

This patch introduces a tagged pages allocator to address the existing problems
of page aliasing on specific platforms and the requirement of page coloring.
It implements an affinity-id aware page manager by separating the runtime page
list into two types: a normal single linked-list and a multi-dimensional affinity-list.
Changes:
- Introduced tagged pages allocator and managing algorithm for affinity pages list
- Modified components to support affinity-id list management
- Updated page allocation and freeing functions to handle tagged pages
- Added configuration options for page affinity block size and debugging
- Modified mmap and elf loading to respect affinity settings
- Enhanced page list management to support multi-dimensional affinity-list

description: Using the vector instruction set to trigger
an illegal instruction exception when ARCH_SISCV_VECTOR=y.
analysis: When initializing the thread stack,
the rt_cw_stack_init function did not enable VS for SSTATUS.
Solution: When ARCH_SISCV_VECTOR=y,
increment the initial value of sstatus by 0x600(SSTATUS_VS).

When building bsp/cvitek/c906_little, compiler reports:
```
.../rt-thread/libcpu/risc-v/rv64/trap.c:
In function 'handle_trap':
.../rt-thread/libcpu/risc-v/rv64/trap.c:106:13:

```
rt_hw_tick_isr()/rt_hw_irq_isr() are implemented by bsp, but
libcpu/risc-v/rv64 doesn't declare them, so compiler warns.
There are three BSPs using 'rv64' (libcpu/risc-v/rv64):
- `bsp/cvitek/c906_little/rtconfig.py`
- `bsp/juicevm/rtconfig.py`
- `bsp/k210/rtconfig.py`
`handle_trap` in `libcpu/risc-v/rv64` is defined as weak.
BSP can use this function directly or define and overload
it by itself.
If bsp use this function directly, bsp need to pay
attention to the fact that three functions will be called
in this function:
- `rt_hw_soft_irq_isr`
- `rt_hw_tick_isr`
- `rt_hw_irq_isr`
In `libcpu/risc-v/rv64`, `rt_hw_soft_irq_isr` has a weak
definition, while the other two do not. This means that
if the bsp does not overload `handle_trap`, bsp must
define `rt_hw_tick_isr` and `rt_hw_irq_isr` itself.
This is also the practice of `bsp/cvitek/c906_little`.
There is also a similar bsp `bsp/k210`, and the form of
`bsp/juicevm` implements `handle_trap` by itself.
It seems that `rt_hw_tick_isr` and `rt_hw_irq_isr` are
not required to be implemented by all BSPs using
`libcpu/risc-v/rv64`. The premise for BSP to implement
them is that it does not overload `handle_trap`. So
declaring `rt_hw_tick_isr` and `rt_hw_irq_isr` with
extern in `libcpu/risc-v/rv64` is not proper.
In addition, the `rt_hw_tick_isr/rt_hw_irq_isr` are only
used by `libcpu/risc-v/rv64`, so it is not worth putting
the declaration in `./include/rthw.h`.
Sum up, the best solution is to add weak definition to
`rt_hw_tick_isr/rt_hw_irq_isr` as existing `rt_hw_soft_irq_isr`.
