The Allwinner SoCs have a display engine composed of several controllers assembled differently depending on the SoC, the number and type of output they have, and the additional features they provide. A number of those are supported in Linux, with the matching bindings. Now that we have the DT validation in place, let's split into separate file and convert the device tree bindings for those controllers to schemas.
