Subject: [PATCH] ASoC: dt-bindings: simple-card: care missing address #address-cells

From: Kuninori Morimoto <kuninori.morimoto.gx@...esas.com>

Current simple-card will get below error,
because it doesn't care about #address-cells at some part.

	DTC     Documentation/devicetree/bindings/sound/simple-card.example.dt.yaml
	Documentation/devicetree/bindings/sound/simple-card.example.dts:171.46-173.15: \
		Warning (unit_address_vs_reg): /example-4/sound/simple-audio-card,cpu@0: \
		node has a unit name, but no reg or ranges property
	Documentation/devicetree/bindings/sound/simple-card.example.dts:175.37-177.15: \
		Warning (unit_address_vs_reg): /example-4/sound/simple-audio-card,cpu@1: \
		node has a unit name, but no reg or ranges property
	...

This patch fixup this issue.
