Bugfix in FEC initialisation:
All MII configuration is done via FEC1 registers. But MII_SPEED was
configured according to FEC used. So if only FEC2 was used, this caused
the real MII_SPEED register in FEC1 to stay uninitalised, what lead
to "mii_send STUCK!" messages. Fix: always configure MII_SPEED on FEC1
only.
