Add a staging driver for Hikey 970 PHY laywer

Hi Greg,

This series add the phy layer needed for the USB stack to work on Hikey 970.

The main difference against v3 is that I'm sending this one via staging.

In order for this phy to actually work properly, we still need to apply one quirk patch at dwc3, which fixes some issues with USB HID driver.

I'm working with Felipe and Rob in order to add the quirk on an approach that would be acceptable for both DT and dwc3 maintainers.

Due to that, I'm not sending the final patch that adds the the needed dt bindings for this board.

Thanks!
Mauro
