Add eth0 device tree node information to da850 by
providing interrupt details and local mac address of eth0.

Can you rebase this to apply to v3.9/dt branch of my tree?

instead of setting interrupt-parent for each node, this can be done once
for soc and child nodes should inherit this property. This needs to be
fixed for existing serial nodes too.

Also, can you take care of pinmux too? we should not be relying on
u-boot to setup the pinmux for us.

Thanks,
Sekhar
