[PATCH v22 7/8] arm64: dts: imx8mq: Add DCSS + HDMI/DP display pipeline

[Laurentiu Palcu <laurentiu.palcu@oss.nxp.com>]

From: Alexander Stein <alexander.stein@ew.tq-group.com>

This adds DCSS + MHDP + MHDP PHY nodes. PHY mode (DP/HDMI) is selected
by the connector type connected to mhdp port@1 endpoint.
