3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rodrigo Vivi <rodrigo.vivi@...el.com>

commit 6b96d705f3cf435b0b8835b12c9742513c77fed6 upstream.

BDW with PCI-IDs ended in "2" aren't ULT, but HALO.
Let's fix it and at least allow VGA to work on this units.

v2: forgot ammend and v1 doesn't compile
