Michael Tretter ecbcceea47 drm/imx: ipuv3-plane: support underlay plane
The IPUv3 overlay plane may be placed over or under the primary plane.

Set the zpos of the primary to an immutable position of 1 to have the
possibility to place the other plane underneath it.

Set the zpos of other planes (the overlay plane) to a mutable value
between 0 (the lowest possible value of a zpos) and directly above the
primary plane with the latter being the default.
