[7/9] drm/i915/scaler: Move pfit scaler into pfit state

Commit Message

From: Ville Syrjälä <[e-mail]>

The plane scaler is stored in the plane state, but the crtc scaler
is stored in the scaler_state. That is a bit incosistent as the
plane state is the state of the consumer, but scaler_state is more
the state of the producer. Move the crtc scaler into the pfit state
which is more analogous to the plane state.
