[PATCH v3] 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 Thine THC63LVD1024 LVDS decoder and
Analog Devices ADV7511W HDMI transmitter...

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

This patch is against the 'renesas-devel-20180423-v4.17-rc2' tag of Simon
Horman's 'renesas.git' repo. It requires the Thine THC63LVD1024 driver in
order to work (the same as the Eagle HDMI patch by Jacopo/Niklas).

Changes in version 3:
- added  Thine THC63LVD1024 device node, updating the respected endpoints;
- merged the I2C pins subnode to the main PFC device node;
- renamed the regulators;
