Subject: [RESEND][PATCH v8 0/6] dwc3 dependencies for HiKey960 USB

Just wanted to send these out again to try to make some progress
on these patches originally by Yu Chen to get HiKey960
dev-board's USB functionality working.

For now I've dropped the hub switching functionality from the
series, as I've not yet been able to come up with a solution to
Rob's objections. So this set focuses just on the dwc3 changes
needed.

The full patchset (including hub switching and dts changes not
submitted here) can be found here:
https://git.linaro.org/people/john.stultz/android-dev.git/log/?id=dcb542a207ac5c5f94729601b2390ca5fbf6f6cd

I'd greatly appreciate any feedback or thoughts!

thanks
-john

New in v8:
* Rob objected to the custom hub switching logic in the
  previous series, so I've dropped it for now.
