hwmon: (nct6755) Add support for NCT6799D 

NCT6799D is mostly compatible to NCT6798D, with minor variations.

Note that NCT6798D and NCT6799D have a new means to select temperature
sources, and to report temperatures from those sources. This is not
currently implemented, meaning that most likely not all temperatures
are reported.
