gpio: acpi: switch to device_for_each_child_node_scoped()

Browse Source 
Switch to device_for_each_child_node_scoped() to simplify the code by
removing the need for a call to fwnode_handle_put() in the error path.

This also prevents possible memory leaks if new error paths are added
without the required call to fwnode_handle_put().
