hwmon: (it87) Add support for IT8620E
IT8620E is mostly compatible to IT7828F. Add generic support for it. IT8620E supports up to 6 fan tachometers and 6 pwm controls. Support for the 6th tachometer and for the additional pwm controls are addded in separate patches. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
