drm/i915: Read hw state into an atomic state struct, v2.

Browse Source 
To make this work we load the new hardware state into the
atomic_state, then swap it with the sw state.

This lets us change the force restore path in setup_hw_state()
to use a single call to intel_mode_set() to restore all the
previous state.

As a nice bonus this kills off encoder->new_encoder,
connector->new_enabled and crtc->new_enabled. They were used only
to restore the state after a modeset.

Changes since v1:
- Make sure all possible planes are added with their crtc set,
  so they will be turned off on first modeset.
