[Intel-gfx] [PATCH] drm/i915: initialize gen6 rps work queue for Ironlake+

[Jesse Barnes]

Looks like I didn't merge Ben's RPS work queue stuff correctly with the
new IRQ split code (diff was sparse enough that git didn't complain).
This should prevent null derefs on ILK+ due to the missing work queue.
