usb: changes for v4.12

With 51 non-merge commits, this is one of the smallest USB Gadget pull
requests. Apart from your expected set of non-critical fixes, and
other miscellaneous items, we have most of the changes in dwc3 (52.5%)
with all other UDCs following with 34.8%.

As for the actual changes, the most important of them are all the
recent changes to reduce memory footprint of dwc3, bare minimum
dual-role support on dwc3 and reworked endpoint count and
initialization routines.
