Subject: [RFC PATCH 6/7] ARM: sun8i: h3: Add DesignWare HDMI controller node

From: Icenowy Zheng <icenowy@...c.io>

The H3 SoC has a DesignWare HDMI controller with some Allwinner-specific
glue and custom PHY.

Since H3 and H5 have same HDMI controller, add related device node in
shared dtsi file.
