iio: palmas: shut up warning about calibration mismatch (due to noise)
Although technically checking for ADC values below 0 is correct, because they are outside of the calibration values, there is usually noise which spuriously fills the console log with error messages if calculated input voltage gets close to 0V. Ignore small negative calculated values, but clamp them to 0. Signed-off-by: H.
