From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
____cacheline_aligned is an insufficient guarantee for non-coherent DMA
on platforms with 128 byte cachelines above L1. Switch to the updated
IIO_ALIGN definition.
Fixes: df1fd2de118e ("iio: max5481: Add support for Maxim digital potentiometers")
