iio: ms_sensors: 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 `battery_low` and `heater_enable`
device attributes of the ms_sensors driver shared code.
