Stefan Agner 78152db78f Add boot from USB mass storage device support for RPi 4 (#746) (#776)
* Backport USB PCIe/XHCI patches to U-Boot 2020.07

Backport relevant patches required to make PCIe/USB XHCI work.

* Backport/integrate PCIe device tree changes from upstream Linux

U-Boot uses the device tree provided by upstream Linux. Make sure the
device tree has the relevant chanages to make VL805 USB controller
reset work.

* Document RPi 4 USB mass storage support (#746)
