I'd say more or less random. Only the F/G suffix usually means Pb-free
or not, the rest doesn't directly translate to "similar enough" I think.

Now, it would be possible to do one common driver for multiple (probably
not all, but many) Winbond Super I/Os, see smscsuperio for an
(admittedly incomplete and a bit convoluted) example, but I had a feeling
you normally do not like such unified drivers all that much ;)

I'd like to drop the definately useless W83627THF first though, if there is
enough interest I can also try to do a more unified driver later.

OK, I'll make another patch to rename _all_ superios which have
multiple irrelevant suffixes accordingly.

Yup, will do after the commit.
