The Linux fec driver needs at least basic phy support to probe and work.
The current qemu mcf_fec emulation has no support for the reading or
writing of the MDIO lines to access an attached phy.
This code adds a very simple set of register results for a fixed phy
setup - very similar to that used on an m5208evb board. This is enough
to probe and identify an emulated attached phy.

Add a base set of bit definitions for the standard MII phy "Auto-Negotiation
Link Partner Ability Register" (ANLPAR).
The original definitions moved into mii.h from the allwinner_emac driver
did not define these.

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.
