drm/i915: Make intel_crtc->config a pointer

Selaa lähdekoodia 
To match the semantics of drm_crtc->state, which this will eventually
become. The allocation of the memory for config will be fixed in a
followup patch. By adding the extra _config field to intel_crtc it was
possible to generate this entire patch with the cocci script below.

v2: Clarify manual changes by splitting them into another patch. (Matt)
    Improve cocci script to generate even more of the changes. (Ander)
