clk / soc: mediatek: Bind clock and gpu driver for mt2712

Browse Source 
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 on
those devices.
