MLK-16813 drm/imx: core: Set driver data to NULL when we bailout from ->bind()
We need to set driver data to NULL when we bailout from ->bind(),
otherwise it would be leaked to the system power management operations
and cause invalid driver data being used there.
Reported-by: Anson Huang <Anson.Huang@nxp.com>
Fixes: 54db5decce17 ("drm/imx: drop deprecated load/unload drm_driver ops")
