Subject: [RFC PATCH v1 8/9] iio: dummy: iio_simple_dummy: Update to event
 unit expanded interface

The IIO events interface has been expanded with an additional parameter,
enabling drivers to handle values in real-world units for IIO event
configuration. Update to the expanded IIO event interface.
