    sna/gen7: Limit threads on HSW GT1
    
    For whatever reason, it seems that for HSW GT1 we cannot specify the
    maximum value of the field and leave it to the hardware to clamp the
    value to the maximum supported. The impact should be zero other than the
    possibilty it workarounds an issue if the hardware doesn't apply the
    limit.
