iio: imu: inv_icm42600: Fix alignment for DMA safety
Partial fix for this driver as a second instance was introduced in
a later patch.
____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.
