drm/i915: Replace vbt edp.support with int_lvds_support
Replace dev_priv->vbt.edp.support with
dev_priv->vbt.int_lvds_support. We'll want to extend its
use beyond the LVDS vs. eDP case in the future.
v2: Nuke the edp.support from parse_edp() (Jani)
Only clear int_lvds_support for gen5+ to preserve
the current behaviour (Jani)
