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.

+Qualcomm Technologies Inc. adreno/snapdragon eDP output
+
+Required properties:
+- compatible:
+ * "qcom,mdss-edp"
+- reg: Physical base address and length of the registers of controller and PLL
+- reg-names: The names of register regions. The following regions are required:
+ * "edp"
+ * "pll_base"
+- interrupts: The interrupt signal from the eDP block.
+- power-domains: Should be <&mmcc MDSS_GDSC>.
+- clocks: device clocks
+ See Documentation/devicetree/bindings/clocks/clock-bindings.txt for details.
+- clock-names: the following clocks are required:
+ * "core_clk"
+ * "iface_clk"
+ * "mdp_core_clk"
+ * "pixel_clk"
+ * "link_clk"
+- #clock-cells: The value should be 1.
+- vdda-supply: phandle to vdda regulator device node
+- lvl-vdd-supply: phandle to regulator device node which is used to supply power
+ to HPD receiving chip
+- panel-en-gpios: GPIO pin to supply power to panel.
+- panel-hpd-gpios: GPIO pin used for eDP hpd.
+
+
+Optional properties:
+- interrupt-parent: phandle to the MDP block if the interrupt signal is routed
+ through MDP block
+
+Example:
