iio: imu: adis16480: add devices to adis16480 driver

Add support for adis16486, adis16487 and adis16489 Six Degrees
of Freedom Inertial Sensors into the existing 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.

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