Supports both big and little cores of RISC-V C906,
but does not support ARM cores. Currently, only UART
drivers are supported on the peripherals.

`rt_object_allocate()` will clear memory after new rt_thread allocate in
`rt_thread_create()`. However, in `rt_thread_init()` the same behavior
is missing, which corrupt the consistence of the API.
Changes:
- Added `memset()` zero for `rt_thread_init()` in the entry

feat: overall implementation of vector irq
This patch generalize the irq handling on up/mp system by adding the
`rt_hw_irq_exit()` & `rt_hw_vector_irq_sched()` API.
Changes:
- Added `rt_hw_irq_exit()` and `rt_hw_vector_irq_sched()` APIs for unified IRQ management.
- Refactored assembly code for both UP and MP systems to use the new IRQ handling flow.
- Removed redundant code and optimized exception handling paths.

This patch addresses the potential issue of uninitialized elements in
the argument vector returned by `lwp_get_command_line_args()`. The
previous implementation could leave `argv` in an inconsistent state
if certain errors occurred, leading to possible undefined behavior.
Changes:
- Replaced `rt_malloc()` with `rt_calloc()` to ensure `argv` is properly initialized.
- Added a consistent error handling path using `goto error_exit` to handle memory allocation failures and string copy errors.
- Ensured `lwp_free_command_line_args()` is called before returning on error, preventing potential memory leaks.

Since the completion is used to sync with ISR mostly, we should set the
default semantic to ISR-safe. So most user will be happy and don't see
any weird behavior in their codes.
Changes:
- Added `rt_completion_wait_noisr` and
`rt_completion_wait_flags_noisr` functions in `completion.h`,
`completion_comm.c`, `completion_mp.c`, and `completion_up.c`.
- The new APIs allow waiting for completions in non-ISR contexts
while ensuring thread context safety.
- Existing documentation and comments were updated to clarify
usage contexts and emphasize restrictions on ISR usage.

This patch replaces SPI flash mount procedure with generic SPI API. This
patch also try to format the external flash on the first mount failure,
in case of empty or invalid flash content is present on the external SPI
flash.
