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 the `child` variable is 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.
