iio: ABI: document accelerometer event attributes

Browse Source 
Add ABI documentation for accelerometer event-related sysfs attributes
exposed by the bmi270 driver. These include threshold, period, and
enable controls for adaptive magnitude (any-motion) and rate of change
(no-motion) event detection.
