Having the ability to describe which physical device things are part of
would probably help a lot with the rendering here - I'm guessing that a
lot of filtering is likely to be things like collapsing down devices not
being looked at right now into a single block in the graph and it'd
probably help with user comprehesibilty provide a mapping back to things
they can see in the physical world.

This doesn't entirely correspond with struct device due to MFD and
multi-function USB stuff but it'd be a good start I expect.
