Subject: [PATCH] kernel: clean up usb gadget support

clean up usb gadget support:
- rename gadget modules so that they appear together and are easier to
  identify as gadget modules
- make usb-lib-composite and usb-gadget hidden as there is no point in
  selecting those without gadget drivers that require them as deps
