drm/i915: Pass intel_atomic_state instead of drm_atomic_state

No functional changes, to align with previous cleanups pass
intel_atomic_state instead of drm_atomic_state.
Also pass this intel_atomic_state with crtc_state to
some of the atomic_check functions.

v2:
* Squash some changes from next patch (Ville)
