usb: gadget: patches for v3.7 merge window

This pull request is large but the biggest part is the first part
of the cleanup on the gadget framework so we have a saner setup
to add configfs support for v3.8.

We have also some more conversions to the new udc_start/udc_stop
which makes us closer from dropping the old interfaces.

USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED are finally gone,
thanks to Michal for his awesome work.

Other than that, we have the usual set of miscellaneous changes
and cleanups involving improvements to debug messages, removal
of duplicated includes, moving dereference after NULL test,
making renesas_hsbhs' irq handler Shared, unused code being dropped,
prevention of sleep-inside-spinlock bugs and a race condition fix
on udc-core.
