USB: ulpi: fix bus-node lookup
Fix bus-node lookup during registration, which ended up searching the whole device tree depth-first starting at the parent (or grand parent) rather than just matching on its children. To make things worse, the parent (or grand-parent) node could end being prematurely freed as well.
