Thanks for your patch!

(If this is to be continued) the PINCTRL_SH_FUNC_GPIO symbol itself, and
all its users, can be removed, too.

This whole hunk should stay (except for the part protected by #ifdef
CONFIG_PINCTRL_SH_FUNC_GPIO), as it is used for validating pin control

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
