drm/amdgpu: Use RLCG to program GRBM_GFX_CNTL during full access time
[Why]
KIQ register init requires GRBM_GFX_CNTL to select KIQ.
[How]
As RLCG accessing registers will save the data of GRBM_GFX_CNTL and restore it.
Use RLCG indirect accessing register method to select grbm instead of mmio directly access.
