From: Andrew Halaney <ahalaney@redhat.com>

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.
