VT-d: suppress UR signaling for further desktop chipsets

This extends commit d6cb14b34f ("VT-d: suppress UR signaling for
desktop chipsets") as per the finally obtained list of affected
chipsets from Intel.

Also pad the IDs we had listed there before to full 4 hex digits.

This is CVE-2013-3495 / XSA-59.
