Subject: [PATCH v6 2/5] hwmon: (core) Add support for humidity min/max
 alarm

Add min_alarm and max_alarm attributes for humidityX to support devices
that can generate these alarms.
Such attributes already exist for other magnitudes such as tempX.

Tested with a ChipCap 2 temperature-humidity sensor.
