drm/amd/display: Fix for the no Audio bug with Tiled Displays
[ Upstream commit 5ceaebcda9061c04f439c93961f0819878365c0f ]
[WHY]
It seems like after a series of plug/unplugs we end up in a situation
where tiled display doesnt support Audio.
[HOW]
The issue seems to be related to when we check streams changed after an
HPD, we should be checking the audio_struct as well to see if any of its
values changed.
