dt-bindings: crypto: Convert ti,omap4-des to DT schema

Convert the TI OMAP DES binding to DT schema format.

Drop "ti,hwmods" as it is not actually used for this binding. Only OMAP2 platforms are using it.

-OMAP SoC DES crypto Module
-
-Required properties:
-
-- compatible : Should contain "ti,omap4-des"
-- ti,hwmods: Name of the hwmod associated with the DES module
-- reg : Offset and length of the register set for the module
-- interrupts : the interrupt-specifier for the DES module
-- clocks : A phandle to the functional clock node of the DES module
-           corresponding to each entry in clock-names
-- clock-names : Name of the functional clock, should be "fck"
-
-Optional properties:
-- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
-	Documentation/devicetree/bindings/dma/dma.txt
-	Each entry corresponds to an entry in dma-names
-- dma-names: DMA request names should include "tx" and "rx" if present
-
-Example:
-	/* DRA7xx SoC */
-	des: des@480a5000 {
-		compatible = "ti,omap4-des";
-		ti,hwmods = "des";
-		reg = <0x480a5000 0xa0>;
-		interrupts = <GIC_SPI 82 IRQ_TYPE_LEVEL_HIGH>;
-		dmas = <&sdma 117>, <&sdma 116>;
-		dma-names = "tx", "rx";
-		clocks = <&l3_iclk_div>;
-		clock-names = "fck";
-	};

My bot found errors running 'make dt_binding_check' on your patch:

/builds/robherring/dt-review-ci/linux/Documentation/devicetree/bindings/crypto/ti,omap4-des.example.dtb: des@480a5000 (ti,omap4-des): 'ti,hwmods' is a required property

doc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/[email protected]

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.
