Check during probe() if a hub supported by the onboard_usb_hub driver is connected to the controller. If such a hub is found create the corresponding platform device. This requires the device tree to have a node for the hub with its vendor and product id (which is not common for USB devices). Further the platform device is only created when CONFIG_USB_ONBOARD_HUB=y/m.
