Update eepro100 net driver's mdio_{read,write} functions 

to take 'struct net_device *' not 'long' as their first
argument.  This makes eepro100 compatible with the standard
MII ethtool API, preparing it for that support.

No functional changes should occur with this patch, if anything
changes at all it is a bug.  (and testing shows no changes...)
