[ Upstream commit 5fdb7c4c7f2691efd760b0b0dc00da4a3699f1a6 ]
[Why] In order to give pin notifications to the sound driver from DM we need to know whether audio is enabled on a stream and what pin it's using from DC.
[How] Expose the instance via stream status if it's a mapped resource for the stream. It will be -1 if there's no audio mapped.
