imp 3ef24c3089 MFp4: Omnibus ed changes 
o Attach AX88x90's MII bus to system, and require its presence.
o Reorg the mii code a little, and move more of it into pccard attachment.
o Eliminate ed_pccard_{read,write}_attrmem in favor of a more appropriate
  function in the pccard layer.
o Update comments to reflect knowledge gained.
o Update how re recognize a NE-2000 ROM.  I found a couple of different
  datasheets that define the structure of the PROM data, so the code's
  old heuristics have been removed, and comments updated to reflect the
  structure.
o Eliminate work around for EC2T.  It is no longer needed, and was wrong
  headed since the EC2T has a Winbound 82C926C in it, not a AX88x90.
o Add copyright to if_ed_pccard.c, since I believe I've re-written more than
  3/4 of it.

# With these changes, all of my 20-odd ed based cards work, except for the
# NetGear FA-410, and I'm pretty sure that's a MII/PHY problem.
