If the driver sets the fwnode in struct gpio_chip, let it take
precedence over the of_node.

By the way, have you tried this on pure DT-less/ACPI-less platform
(CONFIG_OF=n, CONFIG_ACPI=n)? I believe gpio-sim in that case won't work,
because this doesn't affect swnode case, right?

Works just fine on a BeagleBone Black - both the regular GPIO
controllers as well as DT-instantiated gpio-sim.
