thermal: generic-adc: silence info message for IIO_TEMP channels
Since commit d36e2fa0253875 ("thermal: generic-adc: make lookup table optional") "generic-adc-thermal" can be used with an IIO_TEMP channel. In this case the following message is logged at probe time: no lookup table, assuming DAC channel returns milliCelcius Silence this info message if the channel type is known to be in milli celsius. Keep this message when the channel type is unknown or not of type temperature.
