This "audio_clkout" is dummy. Actually, we don't need this dummy clock, and we should use "<&rcar_sound 0>" as AUDIO_CLKOUT, like AUDIO_CLKOUT3 as "<&rcar_sound 3>" which is used on ak4613. But Salvator-X and this ULCB board has very complex connection, especially around CS2000. This means cs2000 requests rcar_sound, and rcar_sound requests cs2000. This audio_clkout exist to avoid probe dead-lock. This is the reason why audio_clkout and rcar_sound::clock-frequency has same value.
