drm/i915: Add primary plane to atomic state in legacy modeset

Browse Source 
Add the primary plane state to the legacy modeset atomic state and use
it when configuring the primary plane in __intel_set_mode(). This is a
first step towards merging the flip path in intel_crtc_set_config() and
__intel_set_mode().

v2: Set crtc to NULL if fb is NULL. (Maarten)
