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

[Louis-Alexis Eyraud]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno at collabora.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.
