The default value of #sound-dai-cells in r8a7778.dtsi is one, while the /sound/simple-audio-card,cpu device node in r8a7778-bockw.dts uses a phandle without any extra cells ("<&rcar_sound>"), causing:

/sound/simple-audio-card,cpu: arguments longer than property asoc-simple-card sound: parse error -22 asoc-simple-card: probe of sound failed with error -22

Override #sound-dai-cells to zero to fix this.
