Currently both USB host uclass and USB gadget uclass are using the same name "usb" which break uclass functions like uclass_get_by_name(). Rename the uclass to "usb_gadget" to fix, also makes bind/unbind by class index (or sequence) working. This breaks the capacity of using "usb" as DT alias sequence numbering which needs a fix afterwards.
