[PATCH 0/1][SRU][OEM-5.14] Fix for rare suspend (s0ix) failures on AMD systems

[Alex Hung]

BugLink: https://bugs.launchpad.net/bugs/1956373

[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.
