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.
