iio: adc: ad7923: 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.
Update the comment to include 'may'.
Note that some other fixes have applied to this line of code
that may complicate automated backporting.
