[PATCH v2 3/3] adds optional script to enable poe passthrough on cpe210

[Tobias Klaus]

The script is only included in ar71xx builds and only executes on the
cpe210 v1.1 hardware.
It is intended to be called from /etc/rc.local.fff_userconfig since the
state of poe passthrough is reset on each reboot.
