drm/amdgpu: enable smart shift on dGPU (v5)
enable smart shift on dGPU if it is part of HG system and
the platform supports ATCS method to handle power shift.
V2: avoid psc updates in baco enter and exit (Lijo)
fix alignment (Shashank)
V3: rebased on unified ATCS handling. (Alex)
V4: check for return value and warn on failed update (Shashank)
return 0 if device does not support smart shift. (Lizo)
V5: rebased on ATPX/ATCS structures global (Alex)
