Device tree best practice is to disable any external interface in the
dtsi and just enable them if needed in the device tree. Thus, disable
both ethernet ports by default and just enable the one used by the EVM
in its device tree.
There is no functional change.

This should also be true for all the other SoCs. But I don't wanted to
touch all the (older) device trees. j722s is pretty new, so there we
should get it right.
