[GIT PULL] rpi: updates for v2021.04

[Matthias Brugger]

Hi Tom,

Please find below the updates for the Raspberry Pi for v202.04. The most
important are the support for Compute Module 4 and RPi400. Apart from that we
now have support for the RNG device found on RPi4.

I run the patches through the gitlab CI:
https://gitlab.denx.de/u-boot/custodians/u-boot-raspberrypi/-/pipelines/6416
https://gitlab.denx.de/u-boot/custodians/u-boot-raspberrypi/-/pipelines/6415

It took quite a while to get all this patches ready for mainline, as the pytests
were failing. This is got fixed by Andy Shevchenko and is now merge upstream, so
everything is green :)

Regards,
Matthias
