Karl Palsson 42e43515c6 usb gadget0: ctrl write/read loopback tests
This is based on linux's gadget0 intel loopback tests, and also github
pr: https://github.com/libopencm3/libopencm3/pull/592

Note that this captures the currently broken control loopback issues on
dwc_otg devices.

See https://github.com/libopencm3/libopencm3/issues/873 and all linked
issues.

Current status is passing on f3, f0, and failing on f4.
