Subject: [PATCH V8 11/12] arm64: dts: imx8mp: add HDMI display pipeline
From: Lucas Stach <l.stach@...gutronix.de>
This adds the DT nodes for all the peripherals that make up the
HDMI display pipeline.

V2: I took this from Lucas' original submission with the following:
Removed extra clock from HDMI-TX since it is now part of the
power domain
Added interrupt-parent to PVI
Changed the name of the HDMI tranmitter to fsl,imx8mp-hdmi-tx
Added ports to HDMI-tx
