iio: accel: sca3000: Fix alignment for DMA safety

Browse source

[ Upstream commit a263456f0e ]

____cacheline_aligned is insufficient guarantee for non-coherent DMA.
Switch to the updated IIO_DMA_MINALIGN definition.

The second alignment marking is left in place to avoid doing more than
the simple fix in this patch.

Fixes: ced5c03d36 ("staging:iio:accel:sca3000 merge files into one.")
Fixes: 152a6a884a ("staging:iio:accel:sca3000 move to hybrid hard / soft buffer design.")
