dt-bindings: nvmem: Convert rockchip-efuse bindings to yaml

Convert the existing rockchip-efuse binding to json-schema. No changes
were done to the binding except for small changes in the documentation
strings.

This deletes the rockchip-efuse.txt binding and replaces it with
rockchip-efuse.yaml.

-= Rockchip eFuse device tree bindings =
-
-Required properties:
-- compatible: Should be one of the following.
-  - "rockchip,rk3066a-efuse" - for RK3066a SoCs.
-  - "rockchip,rk3188-efuse" - for RK3188 SoCs.
-  - "rockchip,rk3228-efuse" - for RK3228 SoCs.
-  - "rockchip,rk3288-efuse" - for RK3288 SoCs.
-  - "rockchip,rk3328-efuse" - for RK3328 SoCs.
-  - "rockchip,rk3368-efuse" - for RK3368 SoCs.
-  - "rockchip,rk3399-efuse" - for RK3399 SoCs.
-- reg: Should contain the registers location and exact eFuse size
-- clocks: Should be the clock id of eFuse
-- clock-names: Should be "pclk_efuse"
-
-Optional properties:
-- rockchip,efuse-size: Should be exact eFuse size in byte, the eFuse
-  size in property <reg> will be invalid if define this property.
-
-Deprecated properties:
-- compatible: "rockchip,rockchip-efuse"
-  Old efuse compatible value compatible to rk3066a, rk3188 and rk3288
-  efuses
-
-= Data cells =
-Are child nodes of eFuse, bindings of which as described in
-bindings/nvmem/nvmem.txt
-
-Example:
-
-	efuse: efuse@ffb40000 {
-		compatible = "rockchip,rk3288-efuse";
-		reg = <0xffb40000 0x20>;
-		#address-cells = <1>;
-		#size-cells = <1>;
-		clocks = <&cru PCLK_EFUSE256>;
-		clock-names = "pclk_efuse";
-
-		/* Data cells */
-		cpu_leakage: cpu_leakage {
-			reg = <0x17 0x1>;
-		};
-	};
-
-= Data consumers =
-Are device nodes which consume nvmem data cells.
-
-Example:
-
-	cpu_leakage {
-		...
-		nvmem-cells = <&cpu_leakage>;
-		nvmem-cell-names = "cpu_leakage";
-	};
