[PATCH v2] device property: preserve usecount for node passed to of_fwnode_graph_get_port_parent()

[Niklas Söderlund]

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.

Fixes: 3b27d00e7b6d7c88 ("device property: Move fwnode graph ops to firmware 
specific locations")
