This series lays the groundwork for more DP MST audio work that will follow. v2: Different solution replacing the enc_to_dig_port() fix (Ville, Lyude). No changes to MST audio enabling and move audio_connector patches. Reordered the patches (Lyude) v3: Different solution to get port from encoder (danvet). Removed locals that are not needed any more. Minor variable renaming clean up. Rebased on dinq. Retained r-b for "start adding dp mst audio" as it does not change. v4: Fixed missing port initialization in intel_sdvo.c Renamed the port enum member from 'attached_port' to 'port' Fixed commit message typos.

Storing the port enum in intel_encoder makes it convenient to know the port attached to an encoder. Moving the port information up from intel_digital_port to intel_encoder avoids unecessary intel_digital_port access and handles MST encoders cleanly without requiring conditional checks for them (thanks danvet).
