usb: gadget: check for streams only for SS udcs
Currently the UASP gadget fails to bind on an UDC which does not provide stream support. This is true for all udc in tree except for dummy and dwc3 since they don't support SuperSpeed. There is no need to test for the availability of stream support on those UDCs because we will never even try to use them. I think it is sane to assume that StreamSupport is always available on SuperSpeed since it is one of the key features. The host side will only allocate on SS so this part is also fine.
