macintosh/ams: 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/macintosh/ams/ams-core.c:53: WARNING: use scnprintf or sprintf. Use sysfs_emit instead of scnprintf or sprintf makes more sense.
