Hi Peter,

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.

The USB3 port should only be enabled in the board files, not the soc one.
We can have a board without USB3 port, so it should be disbaled by default.

Other than that, you can enable it also on stih418-b2199, just tested and it is working.

Thanks,
Maxime
