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.

* bsp:cvitek: add i2c pinmux config for cv18xx_riscv
Pinmux in driver code is controlled by SOC type, bcos driver
code should be general and support all pins defined by SoC.
Pinmux configuration in Kconfig is controlled by BOARD type,
bcos when we operate on board, it does not expose all chip-level
pin signals and we can only use part of them.
Following is I2C signals exported by duo family. Details see

Note: we have not added support for duo-S.
