ASoC: pcm3168a: add hw constraint for capture channel
LEFT_J / I2S only can use TDM. commit 594680ea4a394 ("ASoC: pcm3168a: add hw constraint for channel") commit 3809688980205 ("ASoC: pcm3168a: add HW constraint for non RIGHT_J") added channel constraint for it, but, it was only for playback. This patch adds constraint for capture. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
