[Intel-gfx] [PATCH 7/9] drm/i915: Get the iboost setting based on the port type

[ville.syrjala at linux.intel.com]

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

Program the 'iboost_bit' based on what the VBT says it should be for
the specific port type, rather than assume it's always the same
for DP and HDMI.
