Subject: iio: health: afe4403: retrieve a valid iio_dev in suspend/resume

From: Alison Schofield <amsfield22@gmail.com>

commit a5badd1e97e6caeca78ad74191f12fc923c403a8 upstream.

The suspend/resume functions were using dev_to_iio_dev() to get
the iio_dev. That only works on IIO dev's.  Replace it with spi
functions to get the correct iio_dev.
