When RT_USING_DEBUG is disabled, variables used only in RT_ASSERT statements become unused, triggering -Wunused-but-set-variable compiler warnings. These variables are essential for runtime assertions in debug builds but appear unused in release builds. Example: - Variables used in RT_ASSERT(var != RT_NULL) checks - Affects multiple drivers and components using RT_ASSERT This is a general cleanup to improve code compilation without affecting functionality.

These changes introduce the rt_interrupt_context family, providing a mechanism for managing nested interrupts. The context management ensures proper storage and retrieval of interrupt states, improving reliability in nested interrupt scenarios by enabling context tracking across different interrupt levels. This enhancement is essential for platforms where nested interrupt handling is crucial, such as in real- time or multi-threaded applications. Changes: - Defined rt_interrupt_context structure with context and node fields in `rtdef.h` to support nested interrupts. - Added rt_slist_pop function in `rtservice.h` for simplified node removal in singly linked lists. - Declared rt_interrupt_context_push, rt_interrupt_context_pop, and rt_interrupt_context_get functions in `rtthread.h` to manage the interrupt/exception stack. - Modified AArch64 CPU support in `cpuport.h` to include rt_hw_show_register for debugging registers. - Refactored `_rt_hw_trap_irq` in `trap.c` for context-aware IRQ handling, with stack push/pop logic to handle nested contexts. - Implemented interrupt context push, pop, and retrieval logic in `irq.c` to manage context at the CPU level.

This patch introduces `rt_smp_call_request` API to handle queued requests across cores with user provided data buffer, which provides a way to request IPI through a non-blocking pattern. It also resolved several issues in the old implementation: - Multiple requests from different cores can not be queued in the work object of the target core. - Data racing on `rt_smp_work` of same core. If multiple requests came in turns, or if the call is used by the target cpu, while a new request is coming, the value will be overwrite. - Memory vulnerability. The rt_smp_event is allocated on stack, though the caller may not wait until the call is done. - API naming problem. Actually we don't provide a way to issue an IPI to ANY core in mask. What the API do is aligned to MANY pattern. - FUNC_IPI registering to PIC. Changes: - Declared and configured the new `RT_SMP_CALL_IPI` to support functional IPIs for task requests across cores. - Replaced the single `rt_smp_work` array with `call_req_cores` to manage per-core call requests safely. - Added `_call_req_take` and `_call_req_release` functions for atomic handling of request lifetimes, preventing data race conditions. - Replaced single event handling with a queue-based approach (`call_queue`) for efficient multi-request processing per core. - Introduced `rt_smp_call_ipi_handler` to process queued requests, reducing IPI contention by only sending new requests when needed. - Implemented `_smp_call_remote_request` to handle remote requests with specific flags, enabling more flexible core-to-core task signaling. - Refined `rt_smp_call_req_init` to initialize and track requests with atomic usage flags, mitigating potential memory vulnerabilities.

old phy bus is too simple add phy_bus is not adapt rt_bus framework,so writer a stronger phy bus framework. here is my commit message: add mdio bus and phy bus to kernel,the phy bus use rt_bus framewok ,driver writer can write phy_driver first .when mac driver need to use phy they can register phy_device and pjhy_devie will serach for driver which match by uid and mask,if no driver match with the device that you register,phy_bus will return the genphy to you device,the genphy driver is the general driver for phy,so you can use it but it can not support the capcity of chip it may be cause performance is not up to peak
