Jonathan Cameron 5e6b52de1d iio: addac: ad74413r: Fix alignment for DMA safety
[ Upstream commit 00eb2b8a077062557772234019ecd6045b8b6298 ]

____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.

Update the comment to include 'may'.
