[Intel-gfx] [PATCH] drm/i915: Stop using crtc->index as the pipe

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

The pipe crc code slipped theough the net when we tried to
eliminate all crtc->index==pipe abuses. Remedy that.

And while at it get rid of those nasty intel_crtc+drm_crtc
pointer aliases.
