of: property: Add in-ports/out-ports support to of_graph_get_port_parent()

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.
