    drm/i915: properly reenable gen8 pipe IRQs
    
    This is commit 18c22448d791a5c329528e495f19b639dd7a3dec from Linux 3.17.8
    Original author: Paulo Zanoni <paulo.r.zanoni at intel.com>
    Original commit message:
    
    commit 1180e20606fd7c5d76dc5b2a1594fa51ba5a0f31 upstream.
    
    We were missing the pipe B/C vblank bits! Take a look at
    gen8_de_irq_postinstall for a comparison.
    
    This should fix a bunch of IGT tests.
    
    There are a few more things we could improve on this code, but this
    should be the minimal fix to unblock us.
    
    v2: s/extra_iir/extra_ier/ because IIR doesn't make sense (Ville)
