Subject: drm/amd/display: Enable output_bpc property on all outputs
From: Stylon Wang <stylon.wang@xxxxxxx>
commit 5ae9c378c3d88b40af72f8e8f961808e29f3e70b upstream.
[Why]
Connector property output_bpc is available on DP/eDP only. New IGT tests
would benifit if this property works on HDMI.
[How]
Enable this read-only property on all types of connectors.
