[Why]
This change is a refactor in preparation for adding locking and removing
the requirement for a stream state on the CRTC for enabling CRC capture
to fix igt@kms_plane_multiple@* warnings.
[How]
We can get the aux by finding the matching connector for the CRTC
with the assumption that we're not doing cloning.
