ARM: dts: imx53: Add IPU DI ports and endpoints, move imx-drm node to dtsi
This patch connects IPU and display encoder (VGA, LVDS) device tree nodes, as well as parallel displays on the DISP0 and DISP1 outputs, using the OF graph bindings described in Documentation/devicetree/bindings/media/video-interfaces.txt The IPU ports correspond to the two display interfaces. The order of endpoints in the ports is arbitrary. Since the imx-drm node now only needs to contain links to the display interfaces, it can be moved to the SoC dtsi level. At the board level, only connections between the display interface ports and encoders or panels have to be added.
