Bug Description
[Impact]
AMD Prairie Falcon is the AME Embedded variant of Stoney. It fails to boot up without disable its CGCG feature.
Set 'amdgpu.
[Fix]
Suggestion from AMD that we have to cherry pick this commit which is included in v4.16
fb4bbba27753 drm/amdgpu: re-enable CGCG on CZ and disable on ST
[Test]
Verified on AMD Prairie Falcon platform, system boots up normally.
[Regression Potential]
Low, this commit has been included for more than one and a half year in the upstream, should be pretty safe to include it.
