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.

Skip configure on open since all configs are copied from the current
configuration on device. So we don't bother to set it back to device
again.
Changes:
- test and skip configuration on open() of tty device

[ktime] feat: remove recursion on hrtimer
Replace recursive algorithm with a loop in hrtimer
when determining next timeout event and setup hr timer.

* [DM/feature] Implement PIC irq state { get; set }
There are some common state for irq:
1. Pending: IRQ was triggered, but software not ACK.
2. Active: IRQ was ACK, but not EOI.
3. Masked: IRQ was masked or umasked.

DFS mount auto by kernel parameters
1.Mount the rootfs options by parameters:
- root=: root device, like vda1, sda1, sd0p1, nvme0n0p1...
- rootfstype=: root file system type, like elm, ext, crom...
- rw/ro: root is readonly or all enable, if not have 'rw' flag,
the 'ro' flag is default.
- rootwait: always wait for root device status is OK.
- rootdelay=: mount rootfs delay amount of time (millisecond).
2.Mount the other fs options by `fstab.sh`, it will read the script
after root mount is OK, it's format is a list of mount cmds in MSH:
mount vda2 /mnt elm
mount 192.168.1.1:/ /mnt/remote nfs

ps:在设备初始化阶段不应该存在对硬件的操作
你的解决方案是什么 (what is your solution)
ps:添加一个pin_init函数,在spi设备使用时调用该函数来完成硬件引脚的状态初始化,而不是在设备初始化阶段对硬件进行操作,已经在瑞萨HMI上通过验证
