[PATCH v3 14/16] ASoC: rich-graph-card-sample.dtsi: add DPCM sample (Multi)

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

This patch adds DPCM link Multi-CPU/Codec sample to
rich-graph-card-sample.dtsi.
This sample is assuming MIXer connection.
One note is that Multi-FE is not supported on ASoC

	FE		BE
		****	+-+
	CPU5 -- *  * -- | | -- Codec4
	CPU6 -- *  *	| | -- Codec5
		****	+-+

This reverts commit 674bf04819aaf63b98c83e803ff920e35e315d08.
