[PATCH 07/10] drm/i915: Replace dig_port->port with encoder port for BXT DPLL selection

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Replace dig_port->port with encoder->port in the BXT DPLL selection.
We can do this because both the master encoder and the fake MST encoders
have the same encoder->port value, whereas using dig_port->port only
worked for the master encoder since the fake encoders were't derived
from intel_digital_port. This eliminates the DP MST special case.

Do this by hand because spatch is having problems with the control
flow due to the dig_port assignment happening in two different
branches.
