Others have to answer that one as I don't have that much experience 
either.

You'd have to add a .set_config to gpio_regmap_config and then in

gpio_regmap_register():
   gpio->set_config = config->set_config;

I don't think it makes sense to have a default implementation in 
gpio-regmap,
the variances between "simple" gpio controllers might be too broad.
