[PATCH 2/3] ASoC: dt-bindings: spdif-dit: add missing sound-name-prefix property

[Alexander Stein]

This is used in meson-axg, meson-g12 and meson-gx. Add the property to
the binding.
This fixes the dtschema warning:
audio-codec-0: 'sound-name-prefix' does not match any of the
regexes: 'pinctrl-[0-9]+'
