Force an autonegotiation at attach time for all the attached PHYs for
ed cards. There's a number of minor nits in a lot of the PHYs on the
PC Cards that use the Axis AX88190 or DLink DL10019 and DL10022 chips.
Forcing the autonegotiation doesn't seem to cause problems on the
cards that have sane PHYs, but makes several cards I have work without
further workarounds.

I'm not 100% sure that kicking the PHY and resetting them is the right
thing to do on the media change callback. Other NICs seem to need
this and do similar things.
