Fix child-node lookup during initialisation which was using the wrong OF-helper and ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children.
To make things worse, the parent pci node could end up being prematurely freed as of_find_node_by_name() drops a reference to its first argument. Any matching child interrupt-controller node was also leaked.

v2
- amend commit message and mention explicitly that of_find_node_by_name() drops a reference to the start node
- add Murali's and Lorenzo's acks
This one hasn't shown up in linux-next, so sending a reminder to make sure it doesn't fall between the cracks.
Thanks, Johan
