This series adds support in SoundWire subsystem for:

- stream management
- data port management

- ASoC API to propagate SDW stream
Updates in v3:
- Remove stream state transition checks and redefine stream states
- Update bansk switch routines
- Other nitpicks pointed out by Pierre.
Thanks Vinod and team. This is much better than v2, now the stream
management makes more sense. The only part that isn't clear is that the
framework is supposed to call sdw_stream_add_master() last (to
transition to CONFIGURED state), and that is not explicitly described in
the documentation. The release part also has issues if the master is
handled first, so again I believe there is an assumption that the slaves
will be handled first.
There are still 3 or 4 issues on channel count and remaining comments
not fixed, but this is starting to be reasonably self-explanatory and
useful.
Updates in v2:
- Make ASoC API inlined
- Make stream states as states and not action
- Update the direction enum
- Fix some typos and comment updates
