ASoC: dt-bindings: qcom,wsa883x: Add sound-name-prefix
Commit Message
For multiple speakers attached, it's useful to give them some name.
Sound core already supports this, so reference name-prefix.yaml.

If we need to manually extend the schema like this it should probably be
done for all the CODEC devices.

Several files already do it:
git grep name-prefix.yaml
The trouble for me would be here to identify which devices qualify from
bindings/sound.... everything having #sound-dai-cells?
Best regards,

Pretty much anything could potentially do it, it's a system level thing
for when the same device gets instantiated multiple times. It's most
relevant when something creates user visible controls.
