When using audio from ADV7533 or ADV7535 and describing the audio
card via simple-audio-card, the '#sound-dai-cells' needs to be passed.

Document the '#sound-dai-cells' property to fix the following
dt-schema warning:

imx8mn-beacon-kit.dtb: hdmi@3d: '#sound-dai-cells' does not match any of the regexes: 'pinctrl-[0-9]+'
	from schema $id: http://devicetree.org/schemas/display/bridge/adi,adv7533.yaml#

- Also pass '$ref: /schemas/sound/dai-common.yaml#' (Krzysztof).
