Hi Daniel,
I planned to have single list with nv12 at the end of the list.
And in plane_init report the list as is for nv12 capable planes and
index-1 for non-nv12 planes.
But the earlier (a while ago) feedback from you is, duplication is
cheaper so duplicated them instead of playing trick with array index.
Regarding unification, currently skl_plane_formats[] has different formats
than intel_primary_formats_gen9[]. To have a unified table for both primary
and sprite planes requires testing delta formats on both primary and sprite
planes respectively with respective i-g-t tests. This is not being planned as
part of nv12 feature.
