ar71xx: don't use the unknown LED on the ZCN-1523-5 board

According to #12421, GPIO 1 controls the power
output on the unused lines of the LAN2 port.
Remove the LED definition in order to prevent
possible permanent hardware damage.

If someone needs that, the power-out feature can
be controlled via the GPIO sysfs interface.
