    drm/i915: prefer VBT modes for SVDO-LVDS over EDID

has a silent functional conflict with

commit 990256aec2
Author: Ville Syrjälä <ville.syrjala@linux.intel.com>

    drm: Add probed modes in probe order

in drm-next. W simply need to add the vbt modes before edid modes, i.e. the
other way round than now.
