Subject: drm/amd/display: skip audio setup when audio stream is enabled
Git-commit: c4c3d87be5cbab46039633731d8c5fb203c7a95e
Patch-mainline: v6.1-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
[why]
We have minimal pipe split transition method to avoid pipe
allocation outage.However, this method will invoke audio setup
which cause audio output stuck once pipe reallocate.
[how]
skip audio setup for pipelines which audio stream has been enabled
