drm/amdgpu: Move psp_xgmi_terminate call from amdgpu_xgmi_remove_device to psp_hw_fini
[ Upstream commit 9d705d7741ae70764f3d6d87e67fad3b5c30ffd0 ]
V1:
The amdgpu_xgmi_remove_device function will send unload command
to psp through psp ring to terminate xgmi, but psp ring has been
destroyed in psp_hw_fini.
V2:
1. Change the commit title.
2. Restore amdgpu_xgmi_remove_device to its original calling location.
Move psp_xgmi_terminate call from amdgpu_xgmi_remove_device to
psp_hw_fini.
