iio: imu: adis16400: move trigger handler into adis16400_core 

The trigger handler for the ADIS16400 is very different from the generic
one in the ADIS library. Keeping it in a separate file won't make much
sense once the update_scan_mode function will be made more generic and
moved into the ADIS library.
