I was reviewing again this and I think again I was puzzled why the spec
has them as 0xc5034, ...

Probably same conclusion as I had when I first reviewed this. Maybe it
would be nice to add a comment to PCH_GPIO* saying PCH_GPIOA is used
only for calculation the gpio base and remove the rest. I can send this
is a separate patch, what do you think?

Maybe just have

#define PCH_GPIO_BASE ...

and throw out the PCH_GPIO/GMBUS defines entirely?
