[Intel-gfx] [PATCH v2 08/13] drm/i915: Move plane_state->scaler_id initialization into intel_create_plane_state()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

No point in having each caller of intel_create_plane_state() initialize
the scaler_id to -1. Instead just do it in intel_create_plane_state().

Previously we left scaler_id at 0 for pre-SKL platforms, but I can't
see how initializing it to -1 always would cause any harm.
