[Intel-gfx] [PATCH 1/2] drm/i915: Check dual_link instead of port==A|C for DSI

[ville.syrjala at linux.intel.com]

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

Everywhere else we check for intel_dsi->dual_link instead of the
port mask. So do the same when setting up the lane configuration
in MIPI_PORT_CTRL.
