commit 801f1fa442 "dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports" changed the way the udevice if found. It uses the alias to find a udevice for a given USB port number. In the commit log it was stated that if no alias is provided, the bind order will be used instead. However it doesn't work. Fixing this by adding a call to uclass_get_device() if uclass_get_device_by_seq() fails.
