[PATCH 25/92] iio: adc: max1118: Fix alignment for DMA safety

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

____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: a9e9c7153e96 ("iio: adc: add max1117/max1118/max1119 ADC driver")
