To follow other function drivers, it is safe to remove the check which mean support all possible link speed by default in function driver. Similar change apply to midi2 and uvc. Also in midi and midi2, as there is no descriptor difference between super speed and super speed plus, follow other gadget function drivers, do not allocate descriptor for super speed plus, composite layer will handle it properly.
