[Pdbg] [PATCH v2 05/22] libpdbg: Support paths including virutal nodes

[Amitay Isaacs]

With the presence of virtual nodes, some of the nodes can be reached
from the root using different paths:

  - using virtual nodes (which provide the system device tree view)
  - using the actual hwunits present in the backend (backend device tree)

Both device tree paths should result in the same hardware unit.
