Nicholas Chin c7cb5e434b autoport: Factor out GPIO config generation
Intel chipsets from ICH7 through Lynxpoint use the same GPIO register
format and thus mainboards using using these platforms have similar
gpio.c files. Factor out the code to generate gpio.c from bd82x6x.go so
that it other chipsets added to autoport can use it.

This was originally written by Iru Cai in his Haswell autoport patch in
CB:30890; I have simply split out the code to a separate commit as it is
a separate logical change.

TEST=Generated output is identical before and after this patch when run
against logs from a Dell Latitude E6430
