From: YiPeng Chai <YiPeng.Chai@xxxxxxx> [ 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.
