    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.
