[PATCH v7 22/27] dt-bindings: allwinner: add H616 DE33 mixer binding

The Allwinner H616 and variants have a new display engine revision
(DE33).
The mixer configuration registers are significantly different to the DE3
and DE2 revisions, being split into separate top and display blocks,
therefore a fallback for the mixer compatible is not provided.
Add a display engine mixer binding for the DE33.
