iio: support writing processed values to IIO channels
Add a new function to the IIO API which allows consumers to write
processed values to IIO channels.
This is particularly useful for supporting hardware which has
configurable ADC thresholds. A consumer would be able to change an ADC
threshold by providing a processed value instead of calculating a raw
value.
