Johan Hovold 33c309ebc7 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.

Fixes: ef6a7bcfb0 ("usb: ulpi: Support device discovery via DT")
