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.

Change the overlay to instead assign value "false" on the ti,usb2-only
boolean property, which is of_property_read_bool now evaluates as false.
