The old CLK is can't link all hardware clock cell in system that the
API of layout such as 'set_parent' can't work as expected.
Some hareware clock cell need some flags to prevent some dangerous behaviors, eg:
When a clock cell is link to the PMU, the SoC will power-down if the cell is
disable.
The new CLK can do it, and make the CLK drivers implemented easier from
TRM/DataSheet.

Currently, the print information of this test case fails to demonstrate that
the high-priority thread has preempted the low-priority thread. This is because
when the high-priority thread prints the thread list, there is no information
about the low-priority thread (tlow), as tlow has already completed execution
and been destroyed. Therefore, the current execution logic cannot confirm the
successful completion of the preemption operation.
Solution: After the low-priority thread (tlow) releases the lock, add a busy-wait
loop while(!finish_flag);. At this point, when the high-priority thread (thigh)
prints the thread list information, tlow can be observed in the ready state, indicating
that it has been preempted by thigh.

What is 9PFS (https://en.wikipedia.org/wiki/9P_(protocol)):
9P (or the Plan 9 Filesystem Protocol or Styx) is a network protocol developed for the Plan 9 from Bell Labs distributed operating system as the means of connecting the components of a Plan 9 system. Files are key objects in Plan 9. They represent windows, network connections, processes, and almost anything else available in the operating system.
rt-thread could share filesystem in VM mode with 9pfs such as QEMU...

1.Add the necessary function declarations for SMP enablement and implement the corresponding
functionalities, including rt_hw_secondary_cpu_up, secondary_cpu_entry, rt_hw_local_irq_disable,
rt_hw_local_irq_enable, rt_hw_secondary_cpu_idle_exec, rt_hw_spin_lock_init, rt_hw_spin_lock,
rt_hw_spin_unlock, rt_hw_ipi_send, rt_hw_interrupt_set_priority, rt_hw_interrupt_get_priority,
rt_hw_ipi_init, rt_hw_ipi_handler_install, and rt_hw_ipi_handler.
2.In the two functions (rt_hw_context_switch_to and rt_hw_context_switch) in context_gcc.S,
add a call to rt_cpus_lock_status_restore to update the scheduler information.
3.If the MMU is enabled, use the .percpu section and record different hartids by configuring
special page tables; if the MMU is not enabled, record them directly in the satp register.
Additionally, add dynamic startup based on core configuration.The .percpu section is only used
when both ARCH_MM_MMU and RT_USING_SMP are enabled. However, there is a certain amount of space
waste since no macro guard is added for it in the link script currently.
4.The physical memory of QEMU started in CI is 128MB, so RT_HW_PAGE_END is modified from the
original +256MB to +128MB. Modify the SConscript file under the common64 directory to include
common/atomic_riscv.c in the compilation process.
