Why don't you want this?  Ethernet addresses are supposed to be assigned
to MACs.  It's not a good idea to have a MAC appear at different addresses.
This is why it always assigns the same address.

..... It also makes the decision non-board-specific, so other boards
with dual FEC & SCC ports benefit too:

That's not good either.  I know how EP assigns Ethernet addresses, so
I can do this.  Manufacturers are supposed to supply Ethernet addresses
for every MAC they support.  The "right" way is to have multiple, known
unique addresses assigned to boards that have multiple MACs.  Other
boards may (should) require different assignment methods.
