From: Stanislav Lisovskiy <stanislav.lisovskiy@xxxxxxxxx>
Add changes to DSC which are required for Ultrajoiner.
v2:
-Use correct helper for setting bits for bigjoiner secondary. (Ankit)
-Use primary/secondary instead of master/slave. (Suraj)
v3: Add the ultrajoiner helpers and use it for setting ultrajoiner
bits (Ankit)
v4: Use num_vdsc_instances *= num_joined_pipes (Ville)
