[PATCH 2/4] drm/i915: Clean up gen3 hotplug irq setup

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

For the "always on/unmasked" interrupts we initialize
dev_priv->irq_mask first, then enable_mask. Follow the
same order for the hotplug interrupt so that things are
a bit less confusing.
