hwmon: Add individual alarm files to 4 drivers
hwmon: Add individual alarm files to 4 drivers
Add individual sysfs files for all f71805f, lm63, lm83 and lm90 alarm
and fault conditions. This is a requirement for the planned
chip-independent libsensors. Almost all other hwmon drivers will need
the same improvement.
