Describe HDMI input connector and ADV7612 HDMI decoder installed on
R-Car Gen3 Draak board.

The video signal routing to the HDMI decoder to the video input interface
VIN4 is multiplexed with CVBS input path, and enabled/disabled through
on-board switches SW-49, SW-50, SW-51 and SW-52.

As the default board switches configuration connects CVBS input to VIN4,
leave the HDMI decoder unconnected in DTS.

v3 -> v4:
- Add Laurent's R-b tag.
v2 -> v3:
- Add comment on HDMI output port about the shared CVBS/HDMI video path.
- Add Niklas' R-b tag.
