Shell 65ffe4e13e [libcpu/rv64] feat: unify tick.c
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.

xqyjlj d23dd56692 🐞 fix(ktime): fix wrong boottime
因为tick从中断到设置中间的时延特别大,因此暂不采用tick做基准时间,直接取gtime的cnt做基准时间

sync branch rt-smart. (#6641)
* Synchronize the code of the rt mart branch to the master branch.
  * TTY device
  * Add lwP code from rt-smart
  * Add vnode in DFS, but DFS will be re-write for rt-smart
  * There are three libcpu for rt-smart:
    * arm/cortex-a, arm/aarch64
    * riscv64
