[PATCH v2] drm/amdgpu: Need to set the baco cap before baco reset

I would actually expect the followings

       if (!amdgpu_sriov_vf(adev) && amdgpu_asic_need_reset_on_init(adev)) {         --> no touch for this
+            if (amdgpu_passthrough(adev) && adev->powerplay.pp_funcs && adev->powerplay.pp_funcs->set_asic_baco_cap) {
+                       r = adev->powerplay.pp_funcs->set_asic_baco_cap(adev->powerplay.pp_handle);
+                       if (r) {
+                               dev_err(adev->dev, "set baco capability failed\n");
+                               goto failed;
+                       }
+               }
+

And btw the commit description was lost compared with v1.

Regards,
Evan
