This patch improves the atomicity of context switching by ensuring that
the stack pointer (sp) and thread self updates occur simultaneously.
This enhancement is crucial for maintaining thread safety and
preventing potential inconsistencies during context switches.
Changes:
- Modified `cpuport.h` to use `ARM64_THREAD_REG` for thread self access.
- Added an `update_tidr` macro in `context_gcc.S` to streamline thread ID
updates.
- Adjusted `rt_hw_context_switch_to` and `rt_hw_context_switch` to call
`update_tidr`, ensuring atomic updates during context switches.
- Cleaned up `scheduler_mp.c` by removing redundant thread self
assignments.

add pci api,the pci/pcie driver writer can use this to get resource of current device with flag,there are three flag :
1. PCI_BUS_REGION_F_MEM it mean memory space
2. PCI_BUS_REGION_F_IO it mean io space
3. PCI_BUS_REGION_F_PREFETCH it mean prefetchable memory
