    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.
