the general "rule" is to
- sort by address (the part after the @)
- if that's not present, alphabetically by node-name (not phandle)
  and have address-less things more to the top
- &phandle {} references are sorted alphabetically

And yes in the past there were more creative variants ... like keeping
hdmi-stuff together sounds really great [also to me in the past ;-) ],
but then you end up with a huge list of exceptions.  [0]

So just following the generic sorting thing causes way less confusion,
hence we go that way for new stuff.
