Currently only SKL+ universal planes have the blend mode property.
Assuming it now becomes mandatory for all planes that support
alpha blending we need to add it to cursors on all platforms,
and VLV/CHV primary/sprite planes.
TODO: For VLV/CHV primary/sprite planes we could fairly easily
implement DRM_MODE_BLEND_PIXEL_NONE by remapping the A format
to the corresponding X format, and on CHV pipe B (but not pipes
A/C) we could probably even implement DRM_MODE_BLEND_COVERAGE.
