Now that the mmsys driver is the top-level entry point for the
multimedia subsystem, we could bind the clock and the gpu driver on
those devices that is expected to work, so the drm driver is
intantiated by the mmsys driver and display, hopefully, working again.

If you have this hardware, please kindly provide your tested tag. Only
build tested.

Changes in v2:
- Remove of_match_table

I'm happy to take this through my tree if you provide a Acked-by/Reviewed-by

Sounds good to you?
