The problem is that someone has to manually go and add the device to
every board that needs one and people find that tedious and slightly
inelegant (especially for device tree where not everyone is entirely
happy that it's a good idea to have the node for the board when we
already have the top level machine information saying what board we're
running on).   Jassi's suggestion was that we should have some magic to
automatically generate defaults for the relevant device registrations to
sidestep these issues.
