drm/amdgpu: ungate power gating when system suspend
[Why] During suspend, if GFX DPM is enabled and GFXOFF feature is
enabled the system may get hung. So, it is suggested to disable
GFXOFF feature during suspend and enable it after resume.
[How] Update the code to disable GFXOFF feature during suspend and enable
it after resume.
