Nuno Sa 9e105dd8c0 iio: imu: adis: ensure proper DMA alignment
commit 8e98b87f51 upstream.

Aligning the buffer to the L1 cache is not sufficient in some platforms
as they might have larger cacheline sizes for caches after L1 and thus,
we can't guarantee DMA safety.

That was the whole reason to introduce IIO_DMA_MINALIGN in [1]. Do the same
for the sigma_delta ADCs.
