This patch adds a method for the board to set the MAC address if the environment is not yet set. The environment based MAC addresses are not touched, but if the fdt has an alias set, it is parsed and put into the environment.
E.g. The environment contains ethaddr and eth1addr, and the fdt contains an ethernet1 nothing happens. If the fdt contains ethernet2 however, it is parsed and inserted into the environment as eth2addr.

Ugh. This collides with a function in board/v38b/ethaddr.c and in board/intercontrol/digsy_mtc/digsy_mtc.c
Also, it's so generic, and only gets called by the fdt fixup stuff... This function should probably be named in such a way that its association with fdt is clear.
