        drm/i915: skylake panel fitting using shared scalers

This patch will make sure that we leave scaler_id as 0 for platforms
before skl and set for skl+ only. This way scaler_id check during
check_crtc_state will pass for both prior to skl and skl+ platforms.

v2:
-Leave scaler_id as 0 for gen < 9 (Daniel)
