superio/ite: Unify it8772f with common code
The it8772f is now configured by the much better common code that is
used for other chips in the family as well. This mainly concerns the EC,
the GPIO functionality was not moved to common as it currently lacks a
sane abstraction in any codebase.
The datasheets of the it8772e(f) and it8728f (for reference) were
studied and verified against the common code, adding exceptions where
needed.
