drm/amdgpu: Protect GPU register accesses in powergated state in some paths
[ Upstream commit 39fc2bc4da0082c226cbee331f0a5d44db3997da ]
Ungate GPU CG/PG in device_fini_hw and device_halt to protect GPU
register accesses, e.g. GC registers are accessed in amdgpu_irq_disable_all()
and amdgpu_fence_driver_hw_fini().
