Rock64 vs. USB3 for 14.0-ALPHA2 's Rock64 snapshot vs. device tree update(?)

If I interpret my experiments correctly, 14.0-ALPHA2 no longer
supports the Rock64 USB3 port. This might be a side effect of
importing more modern device tree source files from Linux. (At
least one past import had such an issue for the Rock64, if I
remember correctly.)
