drm/panel: dsi-cm: 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/gpu/drm/panel/panel-dsi-cm.c:251: WARNING: use scnprintf or sprintf. drivers/gpu/drm/panel/panel-dsi-cm.c:271: WARNING: use scnprintf or sprintf. Use sysfs_emit instead of scnprintf or sprintf makes more sense.
