This patch focuses on the ARM64 general context handling code.
The modifications are aimed at enhancing performance by simplifying
context save/restore operations.
Changes include:
- Adjusted stack alignment in `arch_set_thread_context` function.
- Updated `lwp_gcc.S` to reset frame pointer and link register.
- Refined `rt_hw_backtrace_frame_unwind` to handle user space address checks.
- Added `GET_THREAD_SELF` macro in `asm-generic.h`.
- Simplified context saving/restoring in `context_gcc.h` and related files.
- Optimized `rt_hw_context_switch_interrupt` and related assembly routines.

See `components/drivers/include/drivers/watchdog.h`
maco definition of
RT_DEVICE_CTRL_WDT_GET_TIMEOUT
RT_DEVICE_CTRL_WDT_SET_TIMEOUT
RT_DEVICE_CTRL_WDT_GET_TIMELEFT
The wdt timeout time unit is defined as seconds in the API, but
the code incorrectly uses ms.
Correct this and comply with the API definition.

Rootcasue: It's not portable to store integar in a pointer.
Solution: use global _wdt_dev to store the timeout value.

Do unmap before shrink so we don't see mapped entry on page table
insertion, which is not acceptable for riscv implementation of
architecture porting.

[dfs] feat: Mark dirty on unmap for shared mapping
This patch optimizes the pcache varea management by refining the
conditions under which pages are marked dirty, specifically targeting
the unmap operations in the dfs_pcache component. These changes were
necessary to enhance the efficiency of page cache management.
Changes:
- Adjusted include statements in `dfs_pcache.c` for better organization.
- Modified `dfs_aspace_unmap` function:
- Added a check to ensure `varea` is not privately locked before marking a page as dirty.
- Updated `dfs_aspace_page_unmap` function:
- Added a similar check for `varea` lock status before marking a page as dirty.

In the new design, we require the user to manually enter the
PinName (as a string) in menuconfig instead of being given
menu items to select.
The original method will lead to too many menu item-related
macros being defined in the code, causing ifdef and other
codes scatter everywhere in the driver code, which is
inconvenient to maintain.
The new design adds a pinmux driver module to manage the
multiplexing of pins. This patch provides this driver module.
P.S., the reason why users are allowed to specify pinname
in a string instead of the pin number is mainly because
the technical manual provided by the SOC manufacturer
does not have numbers for some pins, only names.

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.

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:

- Defined rt_device_ops structures for partition and sdmmc drivers.
- Updated device initialization to use the ops structure if defined.
