drm/sun4i: Set device driver data at bind time for use in unbind
[ Upstream commit 02b92adbe33e6dbd15dc6e32540b22f47c4ff0a2 ]
Our sun4i_drv_unbind gets the drm device using dev_get_drvdata.
However, that driver data is never set in sun4i_drv_bind.
Set it there to avoid getting a NULL pointer at unbind time.
Fixes: 9026e0d122ac ("drm: Add Allwinner A10 Display Engine support")
