ASoC: dt-bindings: Adjust #sound-dai-cells on TI's single-DAI codecs
[ Upstream commit efb2bfd7b3d210c479b9361c176d7426e5eb8663 ]
A bunch of TI's codecs have binding schemas which force #sound-dai-cells
to one despite those codecs only having a single DAI. Allow for bindings
with zero DAI cells and deprecate the former non-zero value.
