iio: temp: maxim_thermocouple: Fix alignment for DMA safetytemp-alignfixup-branch
____cacheline_aligned is an insufficient guarantee for non-coherent DMA
on platforms with 128 byte cachelines above L1. Switch to the updated
IIO_ALIGN definition
Fixes: 1f25ca11d84a ("iio: temperature: add support for Maxim thermocouple chips")
