[PATCH 5/5] arm64: dts: renesas: v3msk: add DU/LVDS/HDMI support

[Sergei Shtylyov]

Define the V3M Starter Kit board dependent part of the DU and LVDS device
nodes. Also add the device nodes for the Analog Devices ADV7511W HDMI
transmitter -- it's actually connected to the LVDS output via an LVDS
decoder (deliberately omitted here since there's no driver yet anyway).

Based on the original (and large) patch by Vladimir Barinov.
