[Intel-gfx] [PATCH 3/3] drm/i915: Add spurious CRT DMI match for Intel DZ77BH-55K

[ville.syrjala at linux.intel.com]

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

Intel DZ77BH-55K board doest't have a physical VGA connector,
and yet it always detects that something is connected there.
Add it to the DMI blacklist to ignore the spurious detection
results.

Allows me to drop 'video=VGA-1:d' from my kernel cmdline.
