[PATCH v2 2/3] ASoC: meson: t9015: add missing sound-name-prefix property

[Alexander Stein]

This is used in meson-gxl and meson-g12-common .dtsi. Add the property to
the binding.
This fixes the dtschema warning:
audio-controller at 32000: 'sound-name-prefix' does not match any of the
regexes: 'pinctrl-[0-9]+'

All users have set this to "ACODEC", but I am not sure if this value is
mandatory, so I opted to not set a pattern for this property.

Changes in v2:
* None
