x86: Add quirk for Intel DG45ID board to avoid low memory corruption

commit 6aa542a694dc9ea4344a8a590d2628c33d1b9431 upstream.

AMI BIOS with low memory corruption was found on Intel DG45ID
board (Bug 13710). Add this board to the blacklist - in the
(somewhat optimistic) hope of future boards/BIOSes from Intel
not having this bug.
