staging: iio: ad5933: switch buffer mode to software
Since commit 152a6a884ae1 ("staging:iio:accel:sca3000 move
to hybrid hard / soft buffer design.")
the buffer mechanism has changed and the
INDIO_BUFFER_HARDWARE flag has been unused.
Since commit 2d6ca60f3284 ("iio: Add a DMAengine framework
based buffer")
the INDIO_BUFFER_HARDWARE flag has been re-purposed for
DMA buffers.
This driver has lagged behind these changes, and
in order for buffers to work, the INDIO_BUFFER_SOFTWARE
needs to be used.
