Jonathan Cameron faa05ecb13 iio: resolver: ad2s90: Fix alignment for DMA safety 
____cacheline_aligned is an insufficient guarantee for non-coherent DMA
on platforms with 128 byte cachelines above L1.  Switch to the updated
IIO_DMA_MINALIGN definition.

Fixes tag is probably not where the issue was first introduced, but
is likely to be far beyond the point where anyone considers
backporting this fix.

Fixes: 58f08b0af8 ("staging:iio:resolver:ad2s90 general cleanup")
