drm/amdgpu: fix shutdown and poweroff process failed with s0ix
In the shutdown and poweroff opt on the s0i3 system we still need
un-gate the gfx clock gating and power gating before destory amdgpu device.
Fixes: 628c36d7b238e2 ("drm/amdgpu: update amdgpu device suspend/resume sequence for s0i3 support")
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1499
