In majority cases that should be way to go. However in some cases we still need to distinguish between bigjoiner primaries and secondaries(such as DSC register programming). Create correspondent helper functions and start using them, in order be prepared for adding ultrajoiner functionality. v2: Fixed checkpatch warnings (Ankit) v3: Introduce ultrajoiner helpers in next patch. v4: Streamline the helpers and add few more. (Ville) v5: Add comment to clarify that helpers apply to both bigjoiner and uncompressed joiner configurations.
