Dear Kumar Gala,

Move to using the environment variables 'ethaddr', 'eth1addr', etc.. instead of bd->bi_enetaddr, bi_enet1addr, etc.
This makes the code a bit more flexible to the number of ethernet interfaces. Right now we assume a max of 10 interfaces.
How does this match with our very static way of selecting this using 'CONFIG_HAS_ETH<n>' #defines? There is no such thing as CONFIG_HAS_ETH8 anywhere in the code...
oops, forgot about that. I think we just have the code exist always (for CONFIG_OF_LIBFDT)
74xx_7xx, mpc8xx, ppc4xx -- called regardless of CONFIG_HAS_ETHn mpc512x -- called only based on HAS_ETH0 mpc8260, mpc83xx, mpc85xx, mpc86xx -- called if HAS_ETH0 || HAS_ETH1 || HAS_ETH2 || HAS_ETH3
With ETH3 being the max today.
We have a part (p4080) in the works with 8 interfaces (its unlikely we'll have support for all 8 in u-boot, but do want to be ablity to set mac addresses for all 8.)
