You should probably make a seperate driver within GPIO for this and then tie the two together, using an MFD. I appreciate that is more work but it is likely a nicer solution overall.
GPIO chips are small and simple enough that we've not worried about it historically. However my question here is why this is wm9713 specific - the GPIO functionality is part of the AC'97 spec and present on many AC'97 chips so it seems sensible to have something at the AC'97 level. Unfortunately a quick check seems not to show anything indicating this in the AC'97 capability information so we might want to make it opt in.
