iio: temp: max31865: Fix alignment for DMA safety ____cacheline_aligned is an insufficient guarantee for non-coherent DMA on platforms with 128 byte cachelines above L1.

iio: max31865: Use sysfs_emit() sysfs_emit() is preferred over raw s*printf() for sysfs attributes since it knows about the sysfs buffer specifics and has some built-in checks for size and alignment. Use sysfs_emit() to format the custom ``in_filter_notch_center_frequency` and fault_ovuv` device attributes of the max31865 driver.
