util/superiotool: Add Nuvoton NCT6685D/NCT6686D

There doesn't seem to be a datasheet available for the NCT6685D, but
there is one for the NCT6686D. The 85D seems to return the same ID as
the 86D, and the registers do seem to be returning valid data other than
LDN 0xf which returns all 1s. The LDN and register layout appears to be
identical to the NCT6687D-W.

Tested on a Lenovo ThinkCentre M900 with a NCT6685D.
