hwmon: (it87) Introduce configuration field for chip suffix
ITE chips may have 'E', 'F', or both 'E' and 'F' suffixes. Introduce suffic configuration to the it87_devices structure to simplify adding new chips. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
