This patch adds snd-soc-dummy DT binding support.
The devicetree describes the hardware, the snd-soc-dummy is a software only thing and should not be found in the devicetree.
It removes .stream_name from dummy_dai, because "Playback" / "Capture" is very popular naming.
The DAPM will lost correct route settings if other CPU/Codec was using same stream name. And it will be problem when DPCM case. Like below
FE CPU (rsnd): "DAI0 Playback" Codec (dummy): "Playback"
BE CPU (dummy): "Playback" Codec (ak4642): "Playback"
That's something we need to fix, but I don't think removing the stream names is the right way to do this. In a multi CODEC environment you'll quite likely end up with widgets of the same name. Ideally a route endpoint would be expressed by a tuple of DT node and pin name. But I don't think it is possible to mix integer and string elements in a property.
