usb: gadget: udc: Fix duplicate uclass name

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.
