iio: dac: ti-dac082s085: 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: 61011264c1af ("iio: dac: Add Texas Instruments 8/10/12-bit 2/4-channel DAC driver")
