of: property: Add in-ports/out-ports support to of_graph_get_port_parent()
commit 8f1e0d791b5281f3a38620bc7c57763dc551be15 upstream. Similar to the existing "ports" node name, coresight device tree bindings have added "in-ports" and "out-ports" as standard node names for a collection of ports. Add support for these name to of_graph_get_port_parent() so that remote-endpoint parsing can find the correct parent node for these coresight ports too.
