drm/i915: synchronize_irq() against the actual irq

Browse Source 
When eliminating our use of drm_irq_install() I failed to convert
all our synchronize_irq() calls to consult pdev->irq instead of
dev_priv->drm.irq. As we no longer populate dev_priv->drm.irq
we're no longer synchronizing against anything.

v2: Add intel_syncrhonize_irq() (Chris)
