As part of a wider cleanup trying to get rid of OF specific APIs, an incorrect (and partially unrelated) cleanup was introduced.

The goal was to replace a device_for_each_chil_node() loop including an additional condition inside by a macro doing both the loop and the check on a single line.

The snippet:

device_for_each_child_node(dev, child) if (fwnode_property_present(child, "gpio-controller")) continue;

was replaced by:

for_each_gpiochip_node(dev, child)

which expands into:

device_for_each_child_node(dev, child) for_each_if(fwnode_property_present(child, "gpio-controller"))

This change is actually doing the opposite of what was initially expected, breaking the probe of this driver, breaking at the same time the whole boot of Nuvoton platforms (no more console, the kernel WARN()).

Revert these two changes to roll back to the correct behavior.
