Spruce up the ADMtek driver: conver to newbus, miibus and add support

for the AN985 "Centaur" chip, which is apparently the next genetation
of the "Comet." The AN985 is also a tulip clone and is similar to the
AL981 except that it uses a 99C66 EEPROM and a serial MII interface
(instead of direct access to the PHY registers).

Also updated various documentation to mention the AN985 and created
a loadable module.

I don't think there are any cards that use this chip on the market yet:
the datasheet I got from ADMtek has boxes with big X's in them where the
diagrams should be, and the sample boards I got have chips without any
artwork on them.
