USB for v4.20

With 63 non-merge commits, this is not a large merge window for USB
peripheral. The largest changes go to the UVC gadget driver which a
few folks have been improving.

Apart from UVC changes, we have a few more devices being added to
Renesas USB3 and DWC3 controller drivers and a couple minor bug fixes
on other drivers.
