iio: adc: ad7173: add calibration support
The ad7173 family of chips has up to four calibration modes.
Internal zero scale: removes ADC core offset errors.
Internal full scale: removes ADC core gain errors.
System zero scale: reduces offset error to the order of channel noise.
System full scale: reduces gain error to the order of channel noise.
All voltage channels will undergo an internal zero/full scale
calibration at bootup.
System zero/full scale can be done after bootup using the newly created
iio interface 'sys_calibration' and 'sys_calibration_mode'
