drm/amdgpu/mes: Add cleaner shader fence address handling in MES for GFX11
This commit introduces enhancements to the handling of the cleaner shader fence in the AMDGPU MES driver: - The MES (Microcode Execution Scheduler) now sends a PM4 packet to the KIQ (Kernel Interface Queue) to request the cleaner shader, ensuring that requests are handled in a controlled manner and avoiding the race conditions. - The CP (Compute Processor) firmware has been updated to use a private bus for accessing specific registers, avoiding unnecessary operations that could lead to issues in VF (Virtual Function) mode. - The cleaner shader fence memory address is now set correctly in the `mes_set_hw_res_pkt` structure, allowing for proper synchronization of the cleaner shader execution.
