[V7,0/6] soc: imx8mp: Finish support for HDMI

The i.MX8M Plus has an HDMI controller, which depends on several
other systems.  The Parallel Video Interface (PVI) and the
HDMI-TX are already in the Linux-Next staging area 20240209, but
the HDMI PHY driver and several device trees updates are still needed.

This series is adapted from multiple series from Lucas Stach with
edits and suggestions from feedback from various attempts, but it
since it's difficult to use and test them independently,
I merged them into on unified series.  The version history is a
bit ambiguous since different components were submitted at different
times and had different amount of attempts.

The previous attempt I did used the wrong starting point for the PHY,
so this update includes a newer starting point with tags from that version
and fixes from various people's feedback.  I hope I caught them all, but
I apologize if I missed something. Any tags from the previous attempt I
made were intentionally dropped, because of the significant change,
but I kept tags from the newer version I grabbed from patchwork.

Because several items from the last attempt were merged, this
series is only focussed on adding the HDMI PHY driver, and enabling
the power domain, irqsteer interrupt controller, and HDMI pipeline
in the device tree. The version numbers are a bit strange since
these all got pulled from various attempts with different versions,
but I wanted to push them together as a series to complete the pending
work.

This series restarted at V4 based on the version of the PHY driver and
the other drivers and power-domain changes have been applied already.

V7:  Patch 5/7 marks the PVI driver disabled by default to prevent
     EPROBE_DEFER errors.

     No other changes to other patches in the series

V6:  Make the PHY driver depend on COMMON_CLK to fix build errors
     Make LCDIF3 disabled by default since it depends on hardware.

V5 primarily updates feedback from the PHY driver itself, but a small
   adjustment was made to the register size in the device tree.

Hi Adam,

Thanks for your work.
For all the series:
