[PATCH v2 2/3] arm64: dts: renesas: draak: Describe CVBS input

[Jacopo Mondi]

Describe CVBS video input through analog video decoder ADV7180
connected to video input interface VIN4.

The video input signal path is shared with HDMI video input, and
selected by on-board switches SW-53 and SW-54 with CVBS input selected
by the default switches configuration.
