NVS: Add a temp sensor ID and an ACPI Method to set it
This will allow various teams to select which thermal sensor
will control the thermal zones.
Also add a method to notify the thermalzones of a change
so these threshold/sensor methods take effect.
Needs a modified BIOS that uses the NVS TMPS value in
the thermalzone to read a different sensor.
Then, use a kernel driver that contains the following:
/* Adjust temperature sensor id to 2 */
union acpi_object param;
struct acpi_object_list input;
param.type = ACPI_TYPE_INTEGER
param.integer.value = 2
input.count = 1;
input.pointer = ¶m;
acpi_evaluate_object(NULL, "\\TMPU", &input, NULL);
And ensure that the temperature sensor that is being
monitored switches to ID 2.
