This is a rather trivial fix of a problem that happened because i looked
at the wrong spec file when implementing the code.
I added a "Fixes" in the hope that this can be backported as a bugfix.

The count was wrong because i looked at the wrong spec for the chip in
question. I now got access to the spec for that very chip and group7 has
all 8 pins, just like the other groups.

Did you use the NCT6102D / NCT6106D datasheet in a first place ?
If the only difference with NCT6116D is the number of pins on port
GPIO-7, then maybe we should handle it and claim support for this models
as well ?

I do not remember which one, but one of the few one could find online.
Now i have datasheets for two chips directly from the vendor, both
files not publicly available and i am afraid i can not share.

Please hold this patch back until i confirm again. It might be that i
got the model name wrong as well and might have to fix some strings. I
basically started my journey with a preliminary driver i got from
Nuvoton, which maybe made me think i was looking at a NCT6116D while i
was not.
At least that is what the chip IDs from the specs seem to strongly
suggest.
I am sorry for the confusion and will try to clean that up.
Now having access to some of those specs, i can offer to add more
variants without testing. Such support would be in patches on top, not
subject to fixing what we have in stable already. But i would only do
this on demand and have a weird feeling about it, the code might be
trivial but i have no means of testing.

I just sent a v2. I indeed have a 6126D on all of the three boards, and
never had a 6116D. So that v2 does change that name and the pin count
on the last bank.
