This path add support rv1108 rgb output interface driver.

Changes in v2:
- rename rockchip,rgb-mode to rgb-mode;
You can't just drop the vendor. This needs to be documented in a common place that others will find and use. See panel-common.txt or panel-dpi.txt.
Alternatively, you could just drop it and let the panel compatible imply what the mode is.
ok, get it, i will move the rgb-mode to panel and describe it at panel-rgb.txt. the patches will be send soon later.
- delete reg for signle endpoint;

+Required properties: +- compatible: matching the soc type:
- "rockchip,rv1108-rgb";
+Optional properties: +- pinctrl-names: must contain a "lcdc" entry. +- pinctrl-0: pin control group to be used for this interface.
+Required nodes: +- rgb-mode: should be "p888", "p666", "p565", "s888", "s888-dummy"
- p888: output r8-g8-b8 at each dclk cycle for per-pixel
- p666: output r6-g6-b6 at each dclk cycle for per-pixel
- p565: output r5-g6-b5 at each dclk cycle for per-pixel
- s888: output r8-g8-b8 in three dclk cycle for per-pixel
- s888-dmmy: output r8-g8-b8-dummy in four dclk cycle for per-pixel
+The rgb has two video ports described by:
- Documentation/devicetree/bindings/media/video-interfaces.txt
+Their connections are modeled using the OF graph bindings specified in
- Documentation/devicetree/bindings/graph.txt.
+- video port 0 for the VOP input, the remote endpoint maybe vopb/vopl/vop +- video port 1 for either a panel or subsequent encoder
+the panel described by:
- Documentation/devicetree/bindings/display/panel/simple-panel.txt
+Panel other required properties: +- ports for remote rgb output.
+Example:
+panel: panel {
- compatible = "auo,b101ean01";
- enable-gpios = <&gpio7 21 GPIO_ACTIVE_HIGH>;
- ports {
panel_in_rgb: endpoint {remote-endpoint = <&rgb_out_panel>;};- };
+};
+For Rockchip RV1108:
