add support for intel 21145

This chip is some strange abnormal 21143 variant. It really only works with
10 MBit/s halfduplex only and autonegotiation is totally broken in hardware.
Should also have a HomePNA phy, but we don't support that.
for now requires and explicit "media 10BaseT".
if anybody has such a chip please mail me.

nick@ is the only one who has the hardware and did an incredible amount of
testing. Thanks for all the help, Nick!

some hints and ok jason@
