The hardware supports using just a single output while leaving all

really allow specifying a single endpoint@0, because in this case
one must either:

   size cells; or
 - Call the subnode `endpoint@0` and have at least one more other
   endpoint(@1 or @2), and declare address/size cells.

Allow specifying a single `endpoint` subnode, without the `@0`
implicit suffix to suppress warnings happening on this kind of
valid usecase.

This series isn't needed. We've dropped this check from dtc. I'll do a 
sync with upstream.

In any case, it's also a W=1 warning which wouldn't be my top priority.
