iio: frequency: adf4371: 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.

Fixes: 7f699bd14913 ("iio: frequency: adf4371: Add support for ADF4371 PLL")
