drm/i915: Switch fbc over to for_each_new_intel_plane_in_state()

Stop using the old for_each_intel_plane_in_state() type iteration
macro and replace it with for_each_new_intel_plane_in_state().
And similarly replace drm_atomic_get_existing_crtc_state() with
intel_atomic_get_new_crtc_state(). Switch over to intel_ types
as well to make the code less cluttered.

v2: s/plane/i9xx_plane/ etc. (James)
