Actually, that's already gone (but not yet checked in).  I don't even
have #ifdefs for the PHYS.  I scan the MII looking for all PHYs, when
one responds I match the mfg/device ID to a table and go.

There are thing unique to individual boards that still require board
specific #ifdefs.

Many boards don't use 8xx I/O pins for PHY controls.  They have
external hardware registers for this because they use the 8xx pins
for other communication I/O.  This requires minor board specific
code to be included in the driver.
