From: zhikzhai <zhikai.zhai@amd.com>

[ Upstream commit 65fbfb02c2734cacffec5e3f492e1b4f1dabcf98 ]

[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
