Thinking about this I'm not sure that these should go in the device
tree, they're as much talking about what Linux is able to cope with as
they are talking about what the hardware is able to do.  Sometimes
they'll be fixed by the design but they are sometimes also restricted by
what the software is currently capable of.  DRMS is a prime example
here, it depends on how good we are at telling the API about how much
current we're using.
