dt-bindings: bus: Convert Allwinner DE2 bus to a schema

The Allwinner SoCs using the second generation of the display engine have a
bus for that display engine. The bus is supported in Linux, with a matching
Device Tree binding.

Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-Device tree bindings for Allwinner DE2/3 bus
-
-The Allwinner A64 DE2 is on a special bus, which needs a SRAM region (SRAM C)
-to be claimed for enabling the access. The DE3 on Allwinner H6 is at the same
-situation, and the binding also applies.
-
-Required properties:
-
- - compatible:		Should be one of:
-				- "allwinner,sun50i-a64-de2"
-				- "allwinner,sun50i-h6-de3", "allwinner,sun50i-a64-de2"
- - reg:			A resource specifier for the register space
- - #address-cells:	Must be set to 1
- - #size-cells:		Must be set to 1
- - ranges:		Must be set up to map the address space inside the
-			DE2, for the sub-blocks of DE2.
- - allwinner,sram:	the SRAM that needs to be claimed
-
-Example:
-
-	de2@1000000 {
-		compatible = "allwinner,sun50i-a64-de2";
-		reg = <0x1000000 0x400000>;
-		allwinner,sram = <&de2_sram 1>;
-		#address-cells = <1>;
-		#size-cells = <1>;
-		ranges = <0 0x1000000 0x400000>;
-
-		display_clocks: clock@0 {
-			compatible = "allwinner,sun50i-a64-de2-clk";
-			reg = <0x0 0x100000>;
-			clocks = <&ccu CLK_DE>,
-				 <&ccu CLK_BUS_DE>;
-			clock-names = "mod",
-				      "bus";
-			resets = <&ccu RST_BUS_DE>;
-			#clock-cells = <1>;
-			#reset-cells = <1>;
-		};
-	};
