hwmon: (nct6775) add support for TSI temperature registers

Browse source

These registers report CPU temperatures (and, depending on the system,
sometimes chipset temperatures) via the TSI interface on AMD systems.
They're distinct from most of the other Super-IO temperature readings
(CPUTIN, SYSTIN, etc.) in that they're not a selectable source for
monitoring and are in a different (higher resolution) format, but can
still provide useful temperature data.
