drm/i915: don't save all the encoder/crtc state in set_config
We actually only touch the connector -> encoder and encoder -> crtc
linking. So it's enough to just save/restore that.
While at it, also switch to kcalloc to allocate these arrays (omission
in the commit message spotted by Jesse Barnes).
