staging: iio: ad5933: switch buffer mode to software
commit 7d2b8e6aaf9ee87910c2337e1c59bb5d3e3ba8c5 upstream. 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.
