ALSA: hda - Fix stream and channel-ids codec-bus wide

The new sticky PCM parameter introduced the delayed clean-ups of
stream- and channel-id tags.  In the current implementation, this check
(adding dirty flag) and actual clean-ups are done only for the codec
chip.  However, with HD-audio architecture, multiple codecs can be
on a single bus, and the controller assign stream- and channel-ids in
the bus-wide.

In this patch, the stream-id and channel-id are checked over all codecs
connected to the corresponding bus.  Together with it, the mutex is
moved to struct hda_bus, as this becomes also bus-wide.
