hwmon: (ntc_thermistor) fix iio raw to microvolts conversion
The function ntc_adc_iio_read was assuming both a 12 bit ADC and that
pullup_uv is the same as the ADC reference voltage. If either
assumption is false, then the result is incorrect.
Attempt to use iio_convert_raw_to_processed to convert the raw value to
microvolts. It will fail for iio channels that don't support support
IIO_CHAN_INFO_SCALE; in that case fall back to the assumptions.
