hwmon: (nct6775) Rework temperature source and label handling
Instead of checking if a temperature source has a label, use a bit mask to determine if a temperature source is valid for a given chip. This simplifies the code and, if necessary, lets us support chips with unknown or incomplete labels. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
