On the LaCie 2Big Network v2 (net2big_v2) board, the fan alarm is not
wired to the I2C fan controller but to a separe GPIO. This GPIO can be
controlled by using the gpio-fan driver.
This patch adds the gpio-fan alarm description in the net2big_v2 DTS.

Now that the driver part had been merged, I applied this patch on
mvebu/dt.
Thanks,
