V3:
Fixed psp fence and memory issues for the asic
using smu v13_0_2 when removing amdgpu device.

[Why]:
1. psp_suspend->psp_free_shared_bufs->
       psp_ta_free_shared_buf->
           amdgpu_bo_free_kernel->
             ...->amdgpu_bo_release_notify->
                    amdgpu_fill_buffer
   psp will free vram memory used by psp when psp_suspend
   is called. But for the asic using smu v13_0_2, because
   psp_suspend is called before adev->shutdown is set to
   true when removing the first hive device, amdgpu fill_buffer
   will be called, which will cause fence issues when evicting
   all vram resources in amdgpu vram mgr_fini.
2. Since psp_hw_fini is not called after calling psp_suspend
   and psp_suspend only calls psp_ring_stop, the psp ring memory
   will not be released when amdgpu device is removed.

[How]:
1. Set shutdown to true before calling amdgpu_device_gpu_recover,
   then amdgpu_fill_buffer will not be called when psp_suspend is
   called.
2. Free psp ring memory in psp_sw_fini.

SR-IOV may need to load different firmwares for different ASIC inside
VF.
So create a new function in amdgpu_virt to check whether FW load needs
to be skipped.

'free PSP TMR buffer' happens in suspend, but sometimes
in mGPU config, it mixes with PSP resume log printing from
another GPU, which is confusing. So use dev_info instead of
DRM_INFO for printing.
