This will allow to invalidate, destroy backing storage and notify users
of BOs when device is unpluged.

While this looks rather nice it is most likely the wrong approach since 
it doesn't handles other concurrent evictions.

It would most likely be better to add a check calling 
drm_dev_is_unplugged() into amdgpu_bo_move().

Regards,
Christian.

Please add a motivation in the commit message and use imperative wording 
("Allow to invalidate..." instead of "This will allow to")
