The ixp2000 driver for the enp2611 was developed on a board with
three gigabit ports, but some enp2611 models only have two ports (and only one onboard PM3386.) The current driver assumes there are always three ports and so it doesn't work on the two-port version of the board at all. This patch adds a bit of logic to the enp2611 driver to limit the number of ports to 2 if the second PM3386 isn't detected.
