Subject: drm/amdgpu: Add mem_sync implementation for all the ASICs.
Git-commit: 2f9ce2a3860588803dc2ce4c866c06b29f5a201c
Patch-mainline: v5.8-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

Implement the .mem_sync hook defined earlier.

v2: Rename functions
