The following patch tries to fix a small bug that crept in at some
point during 2.5.

None of my 3c592 or 3c597 would work if I didn't force media
type. Instead, it would try to probe MII, looking for a suitable
transceiver, and finaly give up, because these cards really do not
have any sort of MII... :

  EISA: Probing bus 0 at Intel Corp. 82375EB

  EISA: slot 2 : ADP0001 detected.
  EISA: slot 3 : ADP7771 detected.
  EISA: slot 4 : DPTA401 detected.
  EISA: slot 5 : TCM5920 detected.

    ***WARNING*** No MII transceivers found!
  EISA: Detected 4 cards.

With the enclosed patch, it just works, at least on my setup (3c592 on
Alpha, and 3c597 on x86). I haven't been able to test it didn't break
cards with MII, because I do not have such cards in my test boxes...

The patch also removes two useless EISA-only #define I introduced some
time ago.
