iio: core: introduce trough info element for minimum values
The IIO_CHAN_INFO_PEAK info element is used for maximum values and currently there is no equivalent for minimum values. Instead of overloading the existing peak info element, a new info element can be added. In principle there is no need to add a _TROUGH_SCALE element as the scale will be the same as the one required for INFO_PEAK, which in turn is sometimes omitted if a single scale for peaks and raw values is required. Add an IIO_CHAN_INFO_TROUGH info element for minimum values.
