usb: patches for v4.8 merge window

Here's the big pull request for Peripheral stack and
all related drivers.

This time around with 109 non-merge commits mostly
concentrated on drivers/usb/gadget/udc (41.5%) and
drivers/usb/dwc3 (28.1%).

There's a big rework on dwc3's transfer handling
which gave us almost 3x faster USB3 speeds with Mass
Storage on a particular test scenario I measured. We
are also removing platform_data from dwc3 after
converting all users to built-in properties instead.

For the Gadget API, we're just adding tracepoints to
aid debugging activities.

Other than these, there's the usual set of spelling
fixes, minor bug fixes and sparse warnings cleanups.
