drm/i915: Keep display IRQs enabled for encoder suspend/shutdown

Browse Source 
A pending hotplug work or the encoder suspend/shutdown hooks may still
require display IRQs at least for AUX accesses, so keep all display IRQs
except for hotplug IRQs enabled until after intel_hpd_cancel_work() and
the encoder suspend/shutdown hooks are called during system suspend and
shutdown.
