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

ced2284339 Thermal/int3403: Fix thermal hysteresis unit conversion 
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.

925c36bb09 Thermal: ACPI INT3403 thermal driver 
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/.
