hwmon: (ltc4215) make sysfs file match the alarm cause
The ltc4215 driver used the chip's "power good" status bit to provide the power1_alarm file. This is wrong: the chip is really reporting the status of one of the monitored voltages. Change the sysfs file from power1_alarm to in2_min_alarm instead. This matches the voltage that the chip is raising an alarm for. Signed-off-by: Ira W.
