Let me summarize what we can do this independently on any of my
patches and be okay with.

In the regmap GPIO configuration you supply struct fwnode_handle *fwnode.
You can you fwnode API in the actual GPIO controller driver.
Inside gpio-regmap simply do this for now

gc->of_node = to_of_node(config->fwnode);

The last part is an amendment I have told about, but it can be done
later on by switching the entire GPIO chip to use fwnode instead of
of_node.
