usb: changes for v3.18 merge window

Quite big pull request this time. Audio and UVC gadgets
can now be used with our configfs-based binding. We have
three PHY drivers being removed because a new one has been
added using new PHY framework.

Gadget framework got a new ->reset callback preparing for
some other changes to come on next merge window.

A few new drivers came in as well; among those we have a
new UDC driver from Xilinx and two new glue layers for
DWC3 (ST and Qualcomm).

DWC3 also learned about tracepoints which will help debugging
quite a bit.

Other than that, a big series of non-critical fixes and
cleanups.

All patches have been on linux-next for quite a bit of time
and I boot tested these changes on platforms I have access
to and work with mainline.
