we can't have (pipe == crtc->index) assumption in driver in order to support 3 non-contiguous display pipe system.
FIXME: Remove the WARN_ON(drm_crtc_index(&crtc->base) != crtc->pipe) when we will fix all such assumption. changes since RFC: - Added again removed (pipe == crtc->index) WARN_ON. - Pass drm_crtc_index instead of intel pipe in order to call drm_handle_vblank(). v2: - Used drm_crtc_handle_vblank()/drm_crtc_wait_one_vblank() instead of drm_handle_vblank/drm_wait_one_vblank(). [Jani] - Introduced intel_handle_vblank() helper to avoid sprinkle of intel_crtc across irq_handlers. [Ville] v3: - Moved intel_handle_vblank() from header to i915_irq.c.
