dt-bindings: iio: adis16480: add devices to adis16480

Add the adis16486, adis16487 and adis16489 Six Degrees
of Freedom Inertial Sensors to the list of compatible devices
of the adis16480 iio subsystem driver.

adis16486 is similar to adis16485, has the exact same channels
but acceleration and delta velocity scales are different.

adis16487 is fallback compatible with adis16485 and as a
consequence, dt-bindings list was updated to use oneOf.

adis16489 is similar to adis16488 but lacks the magnetometer
and has a different accelerometer scale.
