    drm/qxl: Use pci_is_vga() to identify VGA devices

    Use pci_is_vga() to identify VGA devices instead of a private is_vga()
    function.

    This means qxl will use the VGA arbiter for old PCI_CLASS_NOT_DEFINED_VGA
    (0x0001) devices as well as the PCI_CLASS_DISPLAY_VGA (0x0300) devices it
    recognized previously.

    This probably doesn't make a difference because qxl_pci_driver doesn't
    claim PCI_CLASS_NOT_DEFINED_VGA devices by default, so it's mainly a code
    simplification.
