iio: adc: ad7949: 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.
Note the fixes tag predates some changes to this line of code so
automated application of this fix may fail.
Fixes: 7f40e0614317 ("iio:adc:ad7949: Add AD7949 ADC driver family")
