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.

Again, wrong solution, and conceptually wrong as well from a dt perspective.
The alarm signal should be handled by the g762 driver, and the alarm-gpios
property should be added to the g762 description.
