The required configurations in device-tree were modeled as overlays. The USB-3.1 overlay uses /delete-property/ to unset a boolean property on the usb controller limiting it to USB-2.0 by default. Overlays can not delete a property from the base dtb, therefore this overlay is at this time useless. Convert both overlays into full dts by including the base board dts. While the pcie overlay was functional, both are converted for a consistent user experience when selecting between the two mutually exclusive configurations.
