[RFC PATCH 04/23] ASoC: dt-bindings: qcom,wsa8840: allow one sound DAI cell

[Srinivas Kandagatla]

From: Ravi Hothi <ravi.hothi@xxxxxxxxxxxxxxxx>

The codec now has a VI sense capture DAI next to the playback DAI, so
boards which wire up speaker protection need to address them separately.
Allow '#sound-dai-cells' to be 1 for those, keeping 0 valid for the
boards which only use playback.
