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.

Greg,
I saw that you pulled the previous 2 patches in this series to 6.1, 6.6 and 6.7 kernel branches. I really should have added both of those Fixes tag to this patch too.
Can you please pull in the patch to those stable branches too?
Thanks, Saravana
