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.

feat: [libcpu/c906] support ARCH_REMAP_KERNEL
This change was necessary to enable the remapping of the kernel image to
a high virtual address region on the c906 platform.
Changes:
- Introduced new configuration options `ARCH_REMAP_KERNEL`, and
`ARCH_USING_ASID` under the `ARCH_RISCV64` section.
- Updated MMU initialization and switching functions to incorporate
remapping handling.
- Modified page table setup for proper memory attribute settings.
- Added support for early memory setup, kernel remapping
- Added conditional compilation for ASID support in the `rt_aspace` struct,
since this is not enable currently for most architecture.

* [bsp/allwinner] feat: porting to RT_USING_DEVICE_OPS
This patch ports the codebase to use the RT_USING_DEVICE_OPS structure,
which is required by v5.1.0 Smart kernel, improves modularity and makes
it easier to manage device operations by consolidating them into a
single structure, enhancing maintainability and future scalability.
Changes:
- Added RT_USING_DEVICE_OPS conditionals to partition.c and drv_sdmmc.c.
- Defined rt_device_ops structures for partition and sdmmc drivers.
- Updated device initialization to use the ops structure if defined.
- Replaced direct function calls with rt_dev_control, rt_dev_read, and
rt_dev_write macros where applicable.
- Removed redundant us_delay function from os.c.

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
