Move the fairly heavy eephy_init sequence [which was only done at

attach() and activate() time] into the eephy_reset() routine.  This
means that a bit more work gets done at PHY_RESET time, but it means
also means it gets done in all scenarios.  Why?  For the next commit...
This was in snapshots for about 2 weeks.
