Add the TI afe4404 heart monitor DT bindings documentation. Create health directory created under iio. Signed-off-by: Andrew F. Davis <redacted>
One little point inline - otherwise this is straightforward and looks good to me. Could add cross references to the interrupt and gpio docs. Jonathan

If the sup bit is for supply I'd drop it and just have tx-supply.
