fdt: Rewrite the logic in fdt_fixup_ethernet()
Currently in fdt_fixup_ethernet() the MAC address fix up is handled in a loop of which the exit condition is to test the "eth%daddr" env is not NULL. However this creates unnecessary constrains that those "eth%daddr" env variables must be sequential even if "ethernet%d" does not start from 0 in the "/aliases" node. For example, with "/aliases" node below: aliases { ethernet3 = &enet3; ethernet4 = &enet4; }; "ethaddr", "eth1addr", "eth2addr" must exist in order to fix up ethernet3's MAC address successfully. Now we change the loop logic to iterate the properties in the "/aliases" node. For each property, test if it is in a format of "ethernet%d", then get its MAC address from corresponding "eth%daddr" env and fix it up in the dtb.
