So here is v2 of a few dwc2 fixes that I've been using with HiKey.
I'm not totally sure these are all ideal, but they avoid edge case
issues that we have been running into with switching between
gadget mode and host mode.

I'd guess the first two are potentially -stable material, and
the last might be worth sending to -stable too, as its a relatively
simple fix, but to my understanding the UDC state tracking has
always been broken so its not really a regression. But still.

thanks
