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.

+Samsung LD9040 AMOLED LCD parallel RGB panel with SPI control bus
+
+Required properties:
+  - compatible: "samsung,ld9040"
+  - reg: address of the panel on SPI bus
+  - vdd3-supply: core voltage supply
+  - vci-supply: voltage supply for analog circuits
+  - reset-gpios: a GPIO spec for the reset pin
+  - display-timings: timings for the connected panel according to [1]
+
+The panel must obey rules for SPI slave device specified in document [2].
+
+Optional properties:
+  - power-on-delay: delay after turning regulators on [ms]
+  - reset-delay: delay after reset sequence [ms]
+  - panel-width-mm: physical panel width [mm]
+  - panel-height-mm: physical panel height [mm]
+
+The device node can contain one 'port' child node with one child
+'endpoint' node, according to the bindings defined in [3]. This
+node should describe panel's video bus.
