    VT-d: extend quirks to newer desktop chipsets
    
    We're being told that while on the server side the issue we're trying
    to work around is fixed starting with IvyBridge (another round of
    double checking is going on before we're going to remove the one
    IvyBridge ID that we're currently applying the workaround for), on the
    desktop side even Skylake still requires the workaround. Hence we need
    to add a whole bunch of desktop IDs.
