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.
