usb: patches for v3.20 merge window

Here's the big pull request for Gadgets and PHYs. It's
a total of 217 non-merge commits with pretty much everything
being touched.

The most important bits are a ton of new documentation for
almost all usb gadget functions, a new isp1760 UDC driver,
several improvements to the old net2280 UDC driver, and
some minor tracepoint improvements to dwc3.

Other than that, a big list of minor cleanups, smaller bugfixes
and new features all over the place.
