iio: gyro: adis16080: Fix alignment for DMA safety

Browse source

[ Upstream commit ae6eeb5349 ]

____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.

Fixes tag is inaccurate but unlikely anyone will backport this
beyond that point so I haven't chased the history futher than 2013.
