Drop the manual access to the fwnode of the device to iterate over its child nodes. `device_for_each_child_node` macro provides direct access to the child nodes, and given that they are only required within the loop, the scoped variant of the macro can be used.
Use the `device_for_each_child_node_scoped` macro to iterate over the direct child nodes of the device.

Don't we need to fwnode_handle_put(child) here, since we removed the outer one ?
