[Intel-gfx] [PATCH 04/10] drm/i915: Move vlv/chv display irq code to a more logical place

[ville.syrjala at linux.intel.com]

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

Reshuffle the code a bit to move the vlv/chv display irq functions away
from the main irq hooks, next to the other sub (de,gt,etc.) hooks.
