Synchronise the USB device tree definition with Linux, allowing
the U-Boot control FDT to be used to boot a Linux system with
working USB.
An extra compatible string, "fsl,layerscape-dwc3" is needed
for special handling in U-Boot, so has been added to the
-u-boot.dtsi file. It might be better to add this to the
Linux source bindings.
