drm/amd/pm: skip setting gfx cgpg in the s0ix suspend-resume

Browse Source 
[ Upstream commit 8c45096c60 ]

In the s0ix entry need retain gfx in the gfxoff state,so here need't
set gfx cgpg in the S0ix suspend-resume process. Moreover move the S0ix
check into SMU12 can simplify the code condition check.
