Just another round here trying to push forward a patch series
submitted originally by Yu Chen to get HiKey960 dev-board's USB
functionality working.

The full patchset (including dts changes not submitted here) can
be found here:

I'd greatly appreciate any feedback or thoughts!


New in v7:
* Guillaume Gardet reported issues with CONFIG_USB_ROLE_SWITCH=m
  which to fix required I use IS_ENABLED instead of just #ifdef
  on that config name.
* Added MAINTAINERS file for usb hub misc driver
* Switched the usb hub misc driver bindings to YAML
