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).
v2:
Renamed the port enum member from 'attached_port' to 'port' (danvet)
Fixed missing initialization of port in intel_sdvo.c (danvet)
v3:
Fixed missing initialization of port in intel_crt.c (Ville)
