Subject: [PATCH 5.4 314/320] dt-bindings: display: meson-dw-hdmi: add missing sound-name-prefix property

From: Alexander Stein <alexander.stein@...lbox.org>

commit 22bf4047d26980807611b7e2030803db375afd87 upstream.

This is used in meson-gx and meson-g12. Add the property to the binding.
This fixes the dtschema warning:
hdmi-tx@...3a000: 'sound-name-prefix' does not match any of the
regexes: 'pinctrl-[0-9]+'
