staging:iio:accel:adis16240 move to chan_spec based setup.
For clean drivers its easier to convert to chan_spec based registration than to work around the scan_el attributes going away. Some minor cleanups done whilst here. Untested. V2: IIO_CHAN macro use updated. Signed-off-by: Jonathan Cameron <jic23@cam.ac.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
