Change from EHCI to xHCI on the DFI BayTrail SoM. The xHCI USB hub is connected to an GPIO on the DFI BayTrail SoM. For correct operation, it needs to get reset upon power-up. Otherwise it may happen that the hub is not detected after a software reboot. This patch also configures this GPIO in the dts for correct operation.
