iio: introduce mag_referenced
Some accelerometers that support activity and inactivity events also support a referenced mode, in which the gravitational acceleration is taken as a point of reference before comparing the acceleration to the specified activity and inactivity magnitude. For example, in the case of the ADXL367, for activity detection, the formula is: abs(acceleration - reference) > magnitude Add a new event type that makes this behavior clear.
