[PATCH v5 14/16] ASoC: audio-graph-card2-custom-sample.dtsi: add DPCM sample (Multi)

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

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

This patch adds DPCM link Multi-CPU/Codec sample to
audio-graph-card2-custom-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
		****	+-+
