为什么提交这份PR (why to submit this PR)
Issue: using iperf server with sshd together and the kernel will get stuck occasionally.
taken_list is accessed from other mutex when updating priority.
你的解决方案是什么 (what is your solution)
protect taken_list on shared lock, but not on mutex local spinlock.

After first called from uart open, the dw8250_uart_configure
API cannot be called again. Otherwise, this will mess up the
device, and uart will not act properly to interrupt again.
Analysis: Configure uart device will close recive interrupte,
causing uart device to malfunction.
Solution: After configure uart device, enable the device's
recive interrupte.

This patch fixes GCC build support for FRDM-MCXC444.
* Updated compiler flags to Cortex-M0 without FPU.
* Updated linker script to add RT-Thread const tables.
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.
