Subject: [PATCH v2 1/4] dt-bindings: media: Add bindings for the Amlogic GE2D Accelerator Unit

The GE2D is a 2D accelerator with various features like configurable blitter
with alpha blending, frame rotation, scaling, format conversion and colorspace
conversion.

This adds the bindings for the GE2D version found in the AXG SoCs Family.
