Subject: [PATCH AUTOSEL 5.2 40/85] drm/amd/display: Expose audio inst from DC to DM

From: Nicholas Kazlauskas <nicholas.kazlauskas@....com>

[ 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.
