iio: core: Introduce IIO_CHAN_INFO_CALIBEMISSIVITY
Contact-less IR temperature sensors measure the temperature of an object
by using its thermal radiation. Surfaces with different emissivity
ratios emit different amounts of energy at the same temperature.
IIO_CHAN_INFO_CALIBEMISSIVITY allows the user to inform the sensor of the
emissivity of the object in front of it, in order to effectively measure
its temperature.
A device providing such setting is Melexis's MLX90614:
