Subject: [PATCH 05/12] arm64: dts: mediatek: mt8188: Add DPI1, HDMI, HDMI
 PHY/DDC nodes

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@...labora.com>

Add all of the nodes that are required to enable HDMI output,
including ones describing the HDMI PHY, Controller and DDC,
and the Digital Parallel Interface instance that is internally
connected to the HDMI Controller.

All of the added nodes are disabled by default as usage is
board dependent.
