ALSA: hda/ca0132 - setup/cleanup streams
commit 28fba95087a7f3d107a3a6728aef7dbfaf3fd782 upstream. When a HDMI stream is opened with the same stream tag as a following opened stream to ca0132, audio will be heard from two ports simultaneously. Fix this issue by change to use snd_hda_codec_setup_stream and snd_hda_codec_cleanup_stream instead, so that an inactive stream can be marked as 'dirty' when found with a conflict stream tag, and then get purified.
