I thought cell-index was "deprecated" and referred more to things like
enumerating all the devices on a bus by assigning them a unique ID.
Aliases, on the other hand, allow us to enumerate a subset of devices
that share the same bus with other devices of different types. For
example, how would I know that a device is gsbi1 vs serial1 if they both
used cell-index and they both had the same parent node?
