Subject: [PATCH v2 2/2] doc: iio: ad4695: document buffered read

Update the ad4695 documentation to say that buffered reads are
supported. Since there are 4 possible modes of reading conversion data,
it is useful to know which one is actually being used, namely the
advanced sequencer mode.

v2 changes:

+Device buffers
+==============
+
+This driver supports hardware triggered buffers. This uses the "advanced
+sequencer" feature of the chip to trigger a burst of conversions.
+
+Also see :doc:`iio_devbuf` for more general information.
