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.

No objection, but the new attributes also need to be added to the ABI
documentation at
Documentation/ABI/testing/sysfs-class-hwmon and
Documentation/hwmon/sysfs-interface.rst
Which made me notice that humidityX_alarm isn't documented either.
Please document that attribute as well while you are at it.
Thanks,

Actually there are several attributes without ABI documentation or at
least the attributes enum is much larger than the objects in the ABI
documentation (in testing/sysfs-class-hwmon).
For humidity there is only input, enable, rated_min and rated_max. Are
some attributes not described for a good reason or should all be
documented? the current humidity_attributes contains:
hwmon_humidity_enable -> documented in sysfs-class-hwmon
hwmon_humidity_input -> documented in sysfs-class-hwmon
hwmon_humidity_label
hwmon_humidity_min
hwmon_humidity_min_hyst
hwmon_humidity_max
hwmon_humidity_max_hyst
hwmon_humidity_alarm
hwmon_humidity_fault
hwmon_humidity_rated_min -> documented in sysfs-class-hwmon
hwmon_humidity_rated_max -> documented in sysfs-class-hwmon
I could not find the temperature counterparts of my new additions
(temp_min_alarm and temp_max_alarm).
Should all be added to sysfs-class-hwmon or am I missing some other
document? I am alright adding the ones I mentioned.
