drm/i915/skl+: Scaling not supported in IF-ID Interlace mode
GEN9+ Interlace fetch mode doesn't support pipe/plane scaling,
This patch adds check to fail the flip if pipe/plane scaling is
requested in Interlace fetch mode.
Changes since V1:
- move check to skl_update_scaler (ville)
- mode to adjusted_mode (ville)
- combine pipe/plane scaling check
Changes since V2:
- Indentation fix
- Added TODO to handle/reject NV12 with interlace mode
