Prike Liang d05b0b20a8 drm/amdgpu: fix the hw hang during perform system reboot and reset ...

commit b2a7e9735a upstream.

The system reboot failed as some IP blocks enter power gate before perform
hw resource destory. Meanwhile use unify interface to set device CGPG to ungate
state can simplify the amdgpu poweroff or reset ungate guard.
