iio: adis16480: fix devices that do not support sleep mode 

Not all devices supported by this driver support being put to sleep
mode. For those devices, when calling 'adis16480_stop_device()' on the
unbind path, we where actually writing in the SYNC_SCALE register.

Fixes: 80cbc848c4 ("iio: imu: adis16480: Add support for ADIS16490")
Fixes: 82e7a1b250 ("iio: imu: adis16480: Add support for ADIS1649x family of devices")
