Define shutdown callback for display drm driver, so as to disable all the CRTCS when shutdown notification is received by the driver.
This change will turn off the timing engine so that no display transactions are requested while mmu translations are getting disabled during reboot sequence.

AFAICT atomics is setup in msm_drm_ops::bind and shutdown in msm_drm_ops::unbind.
Are you saying that unbind never triggers? If so, then we should really fix that instead, since this patch seems more like a workaround.
