Analysis: The IRQ_MAX_NR value of cv18xx_risc-v is wrong.
The wrong IRQ_MAX_NR will cause the install of an interrupt
number larger than its value to fail.
Solution: Change IRQ_MAX_NR to the correct value 101 in
the datasheet.

Changes:
- board.c: add static assert for KERNEL_VADDR_START to check if it's valid
- board.h: updated deafult KERNEL_VADDR_START for standard version
- config bsp for v5.2.0 smart requirements
- kconfig: update bsp Kconfig for remap kernel

In the original Sconstruct script, `GetDepend('__STACKSIZE__')`
is placed before the call to `PrepareBuilding()`, which causes
the value of `GetDepend('__STACKSIZE__')` to always be False,
and the value of `__STACKSIZE__` in `link_stacksize.lds` will
not be updated.
Solution: move the call if `PrepareBuilding()` ahead.
Also sync and update the .config and rtconfig.h, plus the
link_stacksize.lds.

The changes unify the tick.c implementations for all risc-v64
architectures, leveraging the CPUTIME feature. This refactoring was
necessary to streamline the codebase, and ensure consistent timer
handling across different platforms.
Changes:
- Updated `Kconfig` in `bsp/cvitek/cv18xx_risc-v` to fix formatting issues.
- Updated .config for BSPs to update `CPUTIME_TIMER_FREQ`
- Updated header of for API `riscv_cputime_init`
- Initialized riscv timer on `rt_hw_tick_init`
- Refactored `tick.c` and `tick.h` in `libcpu/risc-v/t-head/c906` and `libcpu/risc-v/virt64`:
- Replaced direct use of `rdtime` with `clock_cpu_gettime`.
- Removed redundant timer frequency definitions.
- Added static assertions to check the value of `CPUTIME_TIMER_FREQ`.
- Initialized `tick_cycles` based on `CPUTIME_TIMER_FREQ`.
- Integrated `ktime` support for tick initialization.
