So I wonder if it makes sense at all for a driver to both define a gpio
lookup table and then look for each gpio it just defined.

Maybe I am doing it wrong and/or at the wrong level ?

Well ask yourself what you are doing I guess, GPIO is
General Purpose Input Output, a trap some people fall into
is confusing that with their special purpose input/outputs,
and sometimes they are input-only or output-only on top of
that. That is not GPIO.

So what is the use case for these electronics? If it is not
supposed to be used by misc input/output, it is not GPIO,
and it is better for the driver to manage it at will.
