ar71xx: implement switch fix for WD My Net N750

The bootloader on the WD My Net N750 disables the ports on it's internal
AR8327N switch by powering them down. The stock firmware then brings the
ports back up again by starting the auto negotiation process on each
port.

This fix implements just that.

Now that the switch works correctly we can enable the images for this
board.

Flashing from the factory firmware, the factory failsafe loader and
sysupgrade was tested successfully.
