We have something similar already on Freescale parts, but it does
sometimes cause problems.  If the environment ethaddr is already set,
it is left alone.  Otherwise, the MAC address is read from EEPROM.

So we could use CONFIG_PRESERVE_LOCAL_MAC to alter this behavior (i.e.
always use the EEPROM).  However, the current default is already
CONFIG_PRESERVE_LOCAL_MAC, so can we change this to something like
CONFIG_OVERRIDE_LOCAL_MAC?
