The Allwinner H616 and variants have a new display engine revision
(DE33).

Add a display engine bus binding for the DE33. Note that the DE33
requires 3 register blocks instead of 1. To keep things simple
remove the maxItems value for registers for the child nodes and instead
rely on the bindings for the child nodes such as
allwinner,sun8i-a83t-de2-mixer.yaml to enforce the max values.
