The IPUv3 overlay plane may be placed over or under the primary plane. This series allows user space tools to properly detect that the overlay plane may be used as an underlay.
The first patch removes the assumption that the primary plane has the default zpos 0 and the overlay plane has zpos 1. This allows changing the zpos more freely. The second patch changes the default zpos of the planes. The primary plane always has the fixed zpos 1, which allows the overlay plane with zpos 0 to 2 to be placed relative to this fixed primary plane.
