From: "Pandiyan, Dhinakaran" <dhinakaran.pandiyan@intel.com>

BugLink: http://bugs.launchpad.net/bugs/1694665

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)

v4:
Storing port for DVO encoders too.
