hwmon: (gl518sm) Don't create sysfs files for missing features
The early revisions of the GL518SM do not report voltage values for the first 3 voltage channels. We should not create sysfs attributes for these missing features. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
