arm: rpi: Sync rpi dts files from Linux
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.
