iio: gyro: fxas210002c: Fix alignment for DMA safety
____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.
Updated the comment to 'may' require.
Fixes: a0701b6263ae ("iio: gyro: add core driver for fxas21002c")
