hwmon: Define a standard interface for chassis intrusion detection

Browse Source

entries for it, but a standard interface would allow integration with
user-space (namely libsensors.)

automatically when read, this one sticks until cleared by
the user. This is done by writing 0 to the file. Writing
other values is unsupported.
