Sorry not following what the problem is. Yes this is hard block in silicon
and it is silicon v1.

This unit can be used on different silicons too.

There is no way how to detect gpio width.
Pretty much soc_device_match() to some extend could be use to detect which 
silicon it runs but on this particular one you have 3 gpio controllers described 
by this binding (pmc, versal and eio).

Thanks,
