iio: max31856: 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 `fault_ovuv`, `fault_oc` and
`in_temp_filter_notch_center_frequency` device attributes of the max31856
driver.
