drm/amdgpu: fix a GPU hang issue when remove device
When GFXOFF is enabled and GPU is idle, driver will fail to access some
registers. Therefore change to disable power gating before all access
registers with MMIO.
Dmesg log is as following:
amdgpu 0000:03:00.0: amdgpu: amdgpu: finishing device.
amdgpu: cp queue pipe 4 queue 0 preemption failed
