This series adds the phy layer needed by Kirin 970 SoC.

It also adds a GPIO USB3 HUB driver, that is meant to support
the HUB which comes inside with HiKey 960 and 970 designs.

The hub used on Hikey 970 is this one:
	Bus 002 Device 002: ID 0451:8140 Texas Instruments, Inc. TUSB8041 4-Port Hub

While it supports I2C, the driver for it just enables it, depending
on the OTG mode.

- fixes a problem on the past series, where some changes went
  to the wrong patch;
- adds DTS and dt-bindinds required for Hikey 970 USB to work.

For the dt-bindings to work properly, two patches already sent
are required:
   - a patch adding Hikey 970 to dwg3-of-simple driver;
   - a quirks patch for dwc3, which is required for usbhid to work.
    funny enough, such patch is not required by USB sticks.
    I suspect that it affects only INT URB packets, but didn't
    made any tests.
