drm/amd/display: Pass connector id when executing VBIOS CT

commit 433149130c31de3f63b17b4ce08b45dab208f7e8 upstream.

[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
