iio: dac: ad8801: 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: 7f270bc9a2d9 ("iio: dac: AD8801: add Analog Devices AD8801/AD8803 support")
