[PATCH] ASoC: dt-bindings: Adjust #sound-dai-cells on TI's single-DAI codecs

From: Martin Povišer
Date: Tue May 09 2023 - 11:49:40 EST


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.
