Subject: drm/amd/display: Pass connector id when executing VBIOS CT
Git-commit: 433149130c31de3f63b17b4ce08b45dab208f7e8
Patch-mainline: v4.19-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

[why]
Older ASICs require both phys_id and connector_id
to execute bios command table. If we are not passing the
right connector_id - it can lead to a black screen.

[how]
Set connector_obj_id when executing vbios command table
