device property: preserve usecount for node passed to of_fwnode_graph_get_port_parent()
Using CONFIG_OF_DYNAMIC=y uncovered an imbalance in the usecount of the node being passed to of_fwnode_graph_get_port_parent(). Preserve the usecount by using of_get_parent() instead of of_get_next_parent() which don't decrement the usecount of the node passed to it.
