[Impact]
AMD Prairie Falcon is the AME Embedded variant of Stoney. It fails to boot up without disable its CGCG feature.
Set 'amdgpu.cg_mask=0xfffffffb' kernel parameter to disable CGCG

[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]

[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.
