Subject: [PATCH 2881/4131] drm/amd/display: try to find matching audio inst
for enc inst first
[Description]
in eDP+ HDMI/DP clone or extended configuration, audio inst changed from inst 1 to inst0.
No failure related this though, just playback device endpoint inst changed.
Also remove one addition register read.
