dm: usb: udc: Use SEQ_ALIAS to index the USB gadget ports
dfu, fastbot and other usb gadget commands take the USB port index as a parameter. Currently this index is assigned in the order of the driver bindings. Changing this behavior using the SEQ_ALIAS feature. This option assign to the device a SEQ number based on its alias (if it exists) To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing naming convention: use "usb" for the name of the gadget UCLASS_DRIVER (same as for the UCLASS_USB). If no alias is provided, then the index falls back to the order in which the bindings took place.
