Johan Hovold c77b388550 PCI: keystone: Fix interrupt-controller-node lookup ...

commit eac56aa3bc upstream.

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.

Fixes: 0c4ffcfe1f ("PCI: keystone: Add TI Keystone PCIe driver")
