drm/amdgpu: support atcs method powershift (v4)
add support to handle ATCS method for power shift control.
used to communicate dGPU device state to SBIOS.
V2: use defined acpi func for checking psc support (Lijo)
fix alignment (Shashank)
V3: rebased on unified ATCS handling (Alex)
V4: rebased on ATPX/ATCS structures global (Alex)
