thermal: rcar_gen3_thermal: Remove temperature bound

The hardware manual states that the operation of the sensor is not
guaranteed with temperatures above 125°C, not that the readings are
invalid. Remove the bound check and try to deliver temperature readings
even if we are outside the guaranteed operation range.
