ALSA: hda: Properly setup HDMI stream

[ Upstream commit 454abb80e26ab85323a30e52aa7b0ee9aae1d38a ]

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.
