Fix child-node lookup during probe, which 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 pmc node could end up being prematurely freed as of_find_node_by_name() drops a reference to its first argument.

Use the existing reference instead.

This in turn will come in handy as support for new 64-bit ARM SoCs is added. Signed-off-by: Thierry Reding <treding@nvidia.com>
