This devkit is very similar to P3450, except it has less ram, no display
port, and only 3 usb host ports. Derive from P3450 and disable the
hardware that is unavailable.
Gpio PA6 is used to control the hdmi power rail and needs to be on for
hotplug detect to work. This is mapped to the 3.3V usb hub on P3450.
That usb rail is not used here, so delete the regulator to avoid
conflicts.

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade
This patch series was applied (using b4) to base:
Base: using specified base-commit 19272b37aa4f83ca52bdf9c16d5d81bdd1354494
If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
