I tested this patch on mvebu/dt (I needed to reduce the context to apply
the patch due to the changes made by Russell King on this file). I also
set the status of the old binding to "disable" (instead of "okay").

It seems to work with the limited test did:
ifconfig eth1 up
udhcpc -i lan1
iperf -c mylaptop

(same for lan4)

However is there a way to be sure that the new binding is used?
