[PATCH v3 13/16] ASoC: rich-graph-card-sample.dtsi: add DPCM sample (Single)

[Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

This patch adds DPCM link Single-CPU/Codec sample to
rich-graph-card-sample.dtsi.
This sample is assuming MIXer connection.

	FE		BE
		****
	CPU3 -- *  * -- Codec3
	CPU4 -- *  *
		****
