drm/i915: Split skl_update_scaler, v4.

It's easier to read separate functions for crtc and plane scaler state.

Changes since v1:
 - Update documentation.
Changes since v2:
 - Get rid of parameters to skl_update_scaler only used for traces.
   This avoids needing to document the other parameters.
Changes since v3:
 - Rename scaler_idx to scaler_user.
