[PATCH 35/36] drm/i915: Remove ckey/format checks from skl_update_scaler_plane()

[Ville Syrjala]

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

The plane code already takes care to reject scaling when an
unsupported pixel format or color keying is used. No need to replicate
that in the scaler code.
