drm/i915: move cpu_transcoder to the pipe configuration
For a bunch of reason we need to more accurately track this:
- hw pipe state readout for Haswell needs the cpu transcoder.
- We need to know the right cpu transcoder in a bunch of places in
->disable and other modeset callbacks.
In the future we need to add hw state readout&check support, too. But
to avoid ugly merge conflicts do the rote sed job now without any
functional changes.
v2: Preserve the cpu_transcoder value when overwriting crtc->config.
