Currently, we queue an event for signalling HPD connect/disconnect. This
can mean a delay in plug/unplug handling and notifying DRM core when a
hotplug happens.
Drop EV_USER_NOTIFICATION and signal the IRQ event as part of hotplug
handling.
IIUC, the drm_helper_hpd_irq_event() -> drm_bridge_hpd_notify() change
also prevents us from checking *all* connectors if we get *any* HPD?
_unnecessarily_ checking all connectors if we know that HPD was here.
