dt-bindings: consolidate display related bindings
This is a quite large renaming to consolidate display related bindings into a single "display" directory from various scattered locations of video, drm, gpu, fb, mipi, and panel. The prior location was somewhat based on the Linux driver location, but bindings should be independent of that.

-Freescale imx21 Framebuffer
-
-This framebuffer driver supports devices imx1, imx21, imx25, and imx27.
-
-Required properties:
-- compatible : "fsl,<chip>-fb", chip should be imx1 or imx21
-- reg : Should contain 1 register ranges(address and length)
-- interrupts : One interrupt of the fb dev
-
-Required nodes:
-- display: Phandle to a display node as described in
- Documentation/devicetree/bindings/video/display-timing.txt
- Additional, the display node has to define properties:
- - bits-per-pixel: Bits per pixel
- - fsl,pcr: LCDC PCR value
-
-Optional properties:
-- lcd-supply: Regulator for LCD supply voltage.
-- fsl,dmacr: DMA Control Register value. This is optional. By default, the
- register is not modified as recommended by the datasheet.
-- fsl,lpccr: Contrast Control Register value. This property provides the
- default value for the contrast control register.
- If that property is omitted, the register is zeroed.
-- fsl,lscr1: LCDC Sharp Configuration Register value.
-
-Example:
-
- imxfb: fb@10021000 {
- compatible = "fsl,imx21-fb";
- interrupts = <61>;
- reg = <0x10021000 0x1000>;
- display = <&display0>;
- };
-
- ...
-
- display0: display0 {
- model = "Primeview-PD050VL1";
- native-mode = <&timing_disp0>;
- bits-per-pixel = <16>;
- fsl,pcr = <0xf0c88080>; /* non-standard but required */
- display-timings {
- timing_disp0: 640x480 {
- hactive = <640>;
- vactive = <480>;
- hback-porch = <112>;
- hfront-porch = <36>;
- hsync-len = <32>;
- vback-porch = <33>;
- vfront-porch = <33>;
- vsync-len = <2>;
- clock-frequency = <25000000>;
