iio: imu: adis_buffer: Add buffer setup API with buffer attributes

Add new API called devm_adis_setup_buffer_and_trigger_with_attrs() which
also takes buffer attributes as a parameter.
Rewrite devm_adis_setup_buffer_and_trigger() implementation such that it
calls devm_adis_setup_buffer_and_trigger_with_attrs() with buffer
attributes parameter NULL

- * devm_adis_setup_buffer_and_trigger() - Sets up buffer and trigger for
- *					  the managed adis device
+ * devm_adis_setup_buffer_and_trigger_with_attrs() - Sets up buffer and trigger
+ * for the managed adis device with buffer attributes.
  * @adis: The adis device
  * @indio_dev: The IIO device
- * @trigger_handler: Optional trigger handler, may be NULL.
+ * @trigger_handler: Trigger handler: should handle the buffer readings.
+ * @ops: Optional buffer setup functions, may be NULL.
+ * @buffer_attrs: Extra buffer attributes.
  *
  * Returns 0 on success, a negative error code otherwise.
  *
- * This function sets up the buffer and trigger for a adis devices.  If
- * 'trigger_handler' is NULL the default trigger handler will be used. The
- * default trigger handler will simply read the registers assigned to the
- * currently active channels.
+ * This function sets up the buffer (with buffer setup functions and extra
+ * buffer attributes) and trigger for a adis devices with buffer attributes.
