iio: temp: max31865: Fix alignment for DMA safety
[ Upstream commit ecdef5b8317cdf18acb46223e087f04a226fa619 ]
____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: e112dc4e18ea ("iio: temperature: Add MAX31865 RTD Support")
