Bug description:
[Impact]
A rare (~1%) failure has been reported in the community for a period
of time on Renoir platforms with s0ix. This failure was also
corroborated once by a Cezanne user.
[Fix]
In the s0ix entry need retain gfx in the gfxoff state, so skipping
setting gfx cgpg in the S0ix suspend-resume process.
The fix was cherry-picked from 5.16-rc8.
[Test]
This is requested by AMD.
[Where problems could occur]
Low risk. This only affects AMD systems that support s0ix.
