[PATCH] ASoC: dt-bindings: dai-common: Narrow possible sound-dai-cells

[Krzysztof Kozlowski]

Instead of accepting any value for sound-dai-cells, the common DAI
properties schema should narrow them to sane choice.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>

Mostly sound-dai-cells are 0 or 1, but
Documentation/devicetree/bindings/sound/amlogic,aiu.yaml has value of 2.
