Register ohci-at91 driver into Driver Model. In order for the VBUS to stay enabled, a `child_pre_probe` method has been added to overcome the DM core disabling it in `usb_scan_device`: when the generic `device_probe` method is called, the pinctrl is processed once again, undoing whatever changes have been made in our driver's probe method. In order to enable USB on SAMA7G5 the addition of the USB 2.0 PHY drivers were required.
