hwmon: (nct6775) Add support for NCT6798D
NCT6798D is, with the exception of fan and pwm channel configuration registers, similar to other chips of the series. One interesting difference is the chip ID, which is now extended to 13 bit (the 12-bit chip ID value overlaps with the chip ID of NCT6797D). Signed-off-by: Guenter Roeck <linux@roeck-us.net>
