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

Browse Source 
[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
