drm/panel: Add DT bindings for Novatek NT35510-based panels
This adds device tree bindings for the Novatek NT35510-based family of panels. Since several such panels are in existence we define bindings common for all, and define the compatible string for one certain panel (Hydis HVA40WV1). As other panels are discovered and investigated, we can add more compatibles to the binding using oneOf constructions.
