hwmon: (w83627ehf) Only expose in6 or temp3 on the W83667HG
The pin for in6 and temp3 is shared on the W83667HG, so only one of these features can be supported on any given system. Let the driver select which one depending on the temp3 disabled bit. Signed-off-by: Gong Jun <JGong@nuvoton.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
