[PATCH v2 00/11] Add USB support for Hikey 970

Add the PHY layer for Hikey 970 and a misc driver that it is
required for the USB hub to work. The same USB hub is needed
by Hikey 960. 

That's the second version, addressing the points raised by
Mark on the RFC version and adding an extra patch in order for
it to use the dwc3-of-simple driver. Such binding is required,
as using dwc3 directly causes an Serror on ARM.


PS.: I'll be sending the dts bindings later on. We need first to
add a small quirk to dwc3:


I'll be sending a newer version of this specific patch probably
