leds: max5970: Fix unreleased fwnode_handle in probe function
An object initialized via device_get_named_child_node() requires calls
to fwnode_handle_put() when it is no longer required to avoid leaking
memory.
Add the automatic cleanup facility for 'led_node' to ensure that
fwnode_handle_put() is called in all execution paths.
