Laurent Pinchart 3dbf11e421 drm: rcar-du: Clamp DPMS states to on and off 
The intermediate DPMS standby and suspend states are a thing from the
past. They only matter in practice for VGA CRT monitors, and are just a
power saving vs. resume time optimization. Given that they have never
been implemented properly in the rcar-du driver and that the Intel
driver has dropped them on the vga port years ago, it's safe to only
care about the on and off states.

Laurent Pinchart 5e433b6312 drm: rcar-du: Remove LVDS and HDMI encoders chaining restriction 
The rcar-du driver refuses connecting an LVDS output to an HDMI encoder.
There is not technical reason for that restriction, remove it.
