[PATCH] m68knommu: ColdFire FEC eth driver improvements 

A few improvements to the Freescale/ColdFire FEC driver:

. some formatting cleanups
. add support for the FEC device in the ColdFire 523x processor family
. add support for MAC address setting on MOD5272 and M5272C3 boards
. don't re-read the PHY status register many times
. ack status interrupt before reading status register
. move printing init message to after full init (so that the
  ethX name is filled out for printing)

Some parts of this patch submitted by Philippe De Muyter <phdm@macqel.be>
