    drm/i915: Enable hotplug polling after registering the outputs

    Previously we would enable hotplug polling on the outputs immediately
    upon construction. This would allow a very early hotplug event to
    trigger before we had finishing setting up the driver to handle it.
    Instead, move the output polling to the last step of registration, after
    we have set up all handlers, including the fbdev configuration.

    v2: Symmetrically turnoff the hotplug helper in unregister after the
    fbdev is first synchronised then finalized. This stops a late hotplug
    event being processed after the interrupts are disabled.
