There is now support for the multiport USB controller this uses so
enable it.

The board only has a single port hooked up (despite it being wired up to
the multiport IP on the SoC). There's also a USB 2.0 mux hooked up,
which by default on boot is selected to mux properly. Grab the gpio
controlling that and ensure it stays in the right position so USB 2.0
continues to be routed from the external port to the SoC.

If that's your only change to this patch, you should have kept the
Author: field unchanged.

Sure, will do reset-author and resubmit the patch next version.
