Add alternate descriptors support for if_dwc.

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
