drm/i915: Tweak plane ddb allocation tracking
Let's store the plane allocation in a manner which more closely matches how the hw operates. That is, we store the packed/CbCr ddb in one struct, and the Y ddb in another. Currently we're storing packed/Y in one struct, CbCr in the other. This also works pretty well for icl+ where the UV plane is the main plane and the Y plane is subservient to it. Although in this case we do not even use ddb_y as we do the ddb allocation in terms of hw planes. v2: Rebase Reviewed-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220303191207.27931-2-ville.syrjala@linux.intel.com
