Currently when get temperature is queried, both
gThermalMitigationEnable ini and WMI_SERVICE_THERM_THROT service caps are
checked in the driver.
gThermalMitigationEnable ini means the thermal throttling will be done
by driver if enabled and will be done by FW if disabled.
So, set this ini as 0 by default in the driver as thermal throttling
is done by FW and check only WMI_SERVICE_THERM_THROT service while
get temperature is queried.
