This also adds a newbus interface that allows a SoC to override the following settings: - if_dwc specific SoC initialization; - if_dwc descriptor type; - if_dwc MII clock. This seems to be an old version of the hardware descriptors but it is still in use in a few SoCs (namely Allwinner A20 and Amlogic at least). Tested on Cubieboard2 and Banana pi. Tested for regressions on Altera Cyclone by br@ (old version). Obtained from: NetBSD
