From: Alexander Stein <alexander.stein@mailbox.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@c883a000: 'sound-name-prefix' does not match any of the
regexes: 'pinctrl-[0-9]+'
