staging: iio: frequency: ad9832: 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. Whilst here, move the marking to cover
the whole union. That has no functional affect, but makes it slightly
easier to see what is going on.
