The ACPI object definition can contain passive and critical
trip temperature. Export them via thermal sysfs.

Thermal hysteresis represents a temperature difference.
But the original code treats it as a temperature value,
Convert it from tenths of degree Kelvin to Milli-Celsius
by deducing 273200. This is not right.
Kelvin and Celsius have same degree size. From temperature
difference view, the conversion between tenths of degree
Kelvin unit and Milli-Celsius unit is just to multiply 100.

The ACPI INT3403 device objects present on some systems can be used to retrieve
temperature data from thermal sensors. Add a driver registering each INT3403
device object as a thermal zone device and exposing its _TMP, PATx and GTSH
method via the standard thermal control interface under /sys/class/thermal/.
