A big update to the ColdFire FEC ethernet driver.
This has been in the works for a while (and thus tested for
a while too). Fundamentally through there is 3 important
changes:

. support 528x and 527x device families
. allow for multiple FEC devices to be present (for example 2 on the 5274/5)
. support the Kendein 8721 PHY
