From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>
Second fix for this driver due to different introducing patches.
____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: 7f85e42a6c54 ("iio: imu: inv_icm42600: add buffer support in iio devices")
