[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.
