[Intel-gfx] [PATCH 06/17] drm/i915: Eliminate PORT_HOTPLUG_EN setup from gen3/4 irq_postinstall

[ville.syrjala at linux.intel.com]

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

We've already cleared PORT_HOTPLUG_EN in the .irq_preinstall hook
so doing it again in the .irq_postinstall is pointless.
