drm/amd/pm: correct gfx and pcie settings on umd pstate switching(V2)
For entering UMD stable Pstate, the operations to enter rlc_safe
mode, disable mgcg_perfmon and disable PCIE aspm are needed. And
the opposite operations should be performed on UMD stable Pstate
exiting.
V2: take those ASICs(CI/SI/VI) which may not support this into
consideration
