ALSA: hda: Properly setup HDMI stream
Since commit 4005d1ba0a7e ("ASoC: soc-dai: don't call PCM audio ops if the stream is not supported") HDMI playback is broken with avs driver. This happens because for HDMI stream (unlike generic HDA one) channels_min for stream is not set when creating PCMs. Fix this by setting the value based on first available converter.
