[Intel-gfx] [PATCH v2 2/7] drm/i915: Remove (pipe == crtc->index) assumption

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]
