    agp: Do not limit attachment to primary devices
    * PCIS_DISPLAY_VGA really corresponds to the first graphic device
      initialized by the BIOS at boot time.
    * Recent Intel chips contain both AGP and graphic hardware, identified by
      the same PCI ids
    * The agp device thus has no associated PCIS_DISPLAY_VGA flag when the
      Intel graphic device is not set as primary display in BIOS
    * Tested with:
      - ATI Radeon X550 (primary graphic card)
      - Intel Xeon E3-1245v2 (agp device)
