From: Greg Ungerer <g...@uclinux.org>

Create a common set of definitions of address and register values for
ethernet MII phys. A few of the current ethernet drivers have at least
a partial set of these definitions. Others just use hard coded raw
constant numbers.

This initial set is copied directly from the allwinner_emac code.
