hwmon/pc87360 separate alarm files: add therm-min/max/crit-alarms
Adds therm-min/max/crit-alarm callbacks, sensor-device-attribute declarations, and refs to those new decls in the macro used to initialize the therm_group (of sysfs files) The thermistors use voltage channels to measure; so they don't have a fault-alarm, but unlike the other voltages, they do have an overtemp, which we call crit (by convention).
