[PATCH V8 00/12] soc: imx8mp: Add support for HDMI

The i.MX8M Plus has an HDMI controller, but it depends on two
other systems, the Parallel Video Interface (PVI) and the
HDMI PHY from Samsung. The LCDIF controller generates the display
and routes it to the PVI which converts passes the parallel video
to the HDMI bridge. The HDMI system has a corresponding power
domain controller whose driver was partially written, but the
device tree for it was never applied, so some changes to the
power domain should be harmless because they've not really been
used yet.

This series is adapted from multiple series from Lucas Stach with
edits and suggestions from feedback from various series, 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 retries. In an effort to merge them
I used the highest version attempt.
