mfd: janz-cmoio: Replace snprintf in show functions with sysfs_emit

Browse Source 
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.
