Sorry about this, I didn't want to ask you to do this now, it might
have had post-poned to when a new SoC will have to be supported, but..

... I really don't like this, I'm sorry.
I would rather make a 'struct rza_pinctrl_info' or similar which
contains all the fields you now hardcode (number of ports, pins per
port etc) and which is easily extensible in case you need to do so.
I'm sorry this is more work, and again, it might be post-poned imo,
provided you drop this change you have introduced here.
Thanks
