Fix issue that PSP initialization will fail if reload amdgpu module. That's because the PSP ring must be destroyed to be ready for the next time PSP initialization. Changes in v2: - Move psp_ring_destroy before all BOs free (suggested by Ray Huang). Changes in v3: - Check firmware load type, if it is not PSP, we should do nothing in fw_fini(), and of course will not destroy PSP ring too (suggested by Ray Huang).
