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 enum for joiner pipe count instead magic numbers. (Suraj)
-Use primary/secondary instead of master/slave. (Suraj)
