drm/amdkfd: Add user queue eviction restore SMI event
Output user queue eviction and restore event. User queue eviction may be
triggered by svm or userptr MMU notifier, TTM eviction, device suspend
and CRIU checkpoint and restore.
User queue restore may be rescheduled if eviction happens again while
restore.
