arm64: dts: renesas: ulcb-kf: add pcm3168 sound codec
KingFisher has pcm3168 sound codec. This patch enables it. Because pcm3168 can't handle symmetric channel on playback/ capture, we need to handle it as different DAI. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
