drm/amdgpu: enable gfx clock gatings for navi12
enables following gfx clock gating features:
- medium grained clock gating
- medium grained light sleep
- coarse grained clock gating
- cp memory light sleep
- rlc memory light sleep
CGLS (Coarse Grained Light Sleep) will break s3, so don't enable it.
