charger-manager : Add default battery temperature checking funtion.
During the charger manager driver's probing time, it can't succeed
if there's no pre-defined .temperature_out_of_range callback function.
But if fuel gauge supports battery temperature measurement, we
can use it directly. That's what cm_default_get_temp() function does.
With flag measure_batter_temp ON, we normally use cm_default_get_temp()
for .temperature_out_of_range callback funtion.
The TEMP_AMBIENT property is only used for pre-defined one.
