As part of moving to using OF_UPSTREAM and so the upstream dt-bindings
headers we have a number of these headers that are in our include
directory and are currently identical to the versions in dts/upstream.
We can remove these now to prevent future conflicts.

Sync these files, obtained from Linux v5.15.

This adds a devicetree file for rpi_4 which was not there before.

Testing shows no change so far as I can see:
- boots to U-Boot prompt on rpi0, rpi2
- boots to distro on rpi3
- boots to distro on rpi4

I am assuming that syncing with Linux is safe, but the maintainer should
know for sure.

Upstream Linux has received a few device tree updates to the RPi
which we should propagate into the builtin U-Boot one as well to
gain hardware support.

This patch bumps the dts files to their 4.14 Linux counterparts
with the exception of sdhost on 32bit RPi versions. There we stay
with iproc as the sdhost driver is missing in U-Boot.

for the bcm283x family.
