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.

The rcar_sound node is still disabled. So why is this needed?!?
