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.

* Synchronize the code of the rt mart branch to the master branch.
* TTY device
* Add lwP code from rt-smart
* Add vnode in DFS, but DFS will be re-write for rt-smart
* There are three libcpu for rt-smart:
* arm/cortex-a, arm/aarch64
