drm/i915: Only reprobe display on encoder which has received an HPD event (v2)

Browse source

Instead of calling into the DRM helper layer to poll all connectors for
changes in connected displays probe only those connectors which have
received a hotplug event.

v2: Resolved conflicts with changes in previous commits.
    Renamed function and and added a WARN_ON() to warn of
    intel_hpd_irq_event() from being called without
    mode_config.mutex held - suggested by Jani Nikula.
