    drm/i915: Missed interrupt simulation is no more, tell the world

    Using the guc, we cannot disable the user interrupt generation as we use
    it for driving submission. And from Icelake, we no longer have the
    ability to individually mask interrupt generation from each engine,
    disabling our ability to fake missed interrupts.

    In both cases, report back to userspace that the missed interrupt
    generator is no longer available.
