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.
