[PATCH 7/8] arm64: dts: renesas: r8a77995-draak: Add HDMI Out through ADV7511

From: Kieran Bingham <kieran.bingham at ideasonboard.com>

Provide a device node for the ADV7511 as found on the Draak D3 platform.

The ADV7511 is connected to the DU through a parallel mux chip, and is
configurable in hardware whether it is connected to LVDS0 or LVDS1.

Connect through to LVDS0 as a default implementation.
