For the nested interrupt, one thing should decleared:
We are in ISR context, but no meaning we are disabled the interrupts.

This commit refactors the wdog module to use absolute time representation internally. The main improvements include:
1. Fixed recursive watchdog handling caused by calling wd_start within watchdog timeout callback function.
2. Simplified timer processing to improve performance and enhance code readability.
3. Improved accuracy of timers.
4. Reduced critical section and interrupt disable time, improving real-time performance.

The register context is not needed, the original idea was to provide
the user stack pointer for signal handler delivery, but the user stack
can be obtained via sp_el0 so the context registers are not needed.
SP0 is not stored upon exception entry anyways, so this code is just
completely redundant and wrong.
reason:
In SMP, when a context switch occurs, restore_critical_section is executed.
To reduce the time taken for context switching, we directly pass the required
parameters to restore_critical_section instead of acquiring them repeatedly.

reason:
In the SMP, when a context switch occurs, restore_critical_section is executed.
In order to reduce the time taken for context switching,
we inline the restore_critical_section function.
Given that restore_critical_section is small in size
and is called from only one location, inlining it does not increase the size of the image.

The vaddr field in TLBI means: Bits[55:12] of the virtual address to match.
This basically means the page offset of the virtual address, so the input
vaddr must be shifted to the page offset.
Reference TLBI VALE1IS register description from ARMv8-A reference manual.
The 12:0 bits in table descriptors are RES0 and AF is the 10th bit, so
it is not valid to set it in this case.
Fix this by moving AF to the common MMU_MT_NORMAL_FLAGS field
Make sure the user L1 page is updated to system memory when the kernel
mappings are copied.
Also, flush the I-cache when switching address environments.

Add new driver frameworks: force feedback for vibrator, like linux,
unify vendor vibrator driver using.
Incorporating a force feedback-based driving framework to replace the
conventional driver/motor setup for controlling vibrators not only
enhances the precision and responsiveness of the haptic feedback but
also aligns better with the advancements in Linux-based driver systems.
