drm/amdgpu/mes: Add cleaner shader fence address handling in MES for GFX12
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.
