mfd: janz-cmoio: Replace snprintf in show functions with sysfs_emit
show() must not use snprintf() when formatting the value to be
returned to user space.
Fix the following coccicheck warning:
drivers/mfd/janz-cmodio.c:157: WARNING: use scnprintf or sprintf.
Use sysfs_emit instead of scnprintf or sprintf makes more sense.
