If these two cases look the same from a hardware point of view (one
external interface connected to the CODEC, one block within the SoC
which happens to be able to deal with multiple streams of audio) then
they should look the same from a DT point of view.  The fact that the
block can handle multiple streams of audio shouldn't be relevant to the
DT bindings.
