[PATCH 4/6] ARM: DT: STi: STiH407: Add dwc3 usb3 DT node.

[Peter Griffin <peter.griffin@linaro.org>]

Now that both usb2 and usb3 phy drivers, and also the ST dwc3 glue code
are all present upstream, we can add the dwc3 DT node and have a working
usb3 controller on stih407-b2120 and stih410-b2020.
