Subject: [PATCH 4/4] Revert "drm/amdgpu: workaround the TMR MC address issue (v2)"
This reverts commit 34a33d4683cba7ba63c894132efb1998c0217631.
34a33d4683cba7ba63c894132efb1998c0217631 was a driver workaround when PSP firmware was not ready. Now the PSP fw is ready so we revert this driver workaround.
