dt-bindings: crypto: Convert stm32 HASH bindings to json-schema

* STMicroelectronics STM32 HASH

Required properties:

- compatible: Should contain entries for this and backward compatible

  HASH versions:

  - "st,stm32f456-hash" for stm32 F456.

  - "st,stm32f756-hash" for stm32 F756.

- reg: The address and length of the peripheral registers space

- interrupts: the interrupt specifier for the HASH

- clocks: The input clock of the HASH instance

Optional properties:

- resets: The input reset of the HASH instance

- dmas: DMA specifiers for the HASH. See the DMA client binding,

	 Documentation/devicetree/bindings/dma/dma.txt

- dma-names: DMA request name. Should be "in" if a dma is present.

- dma-maxburst: Set number of maximum dma burst supported

Example:

hash1: hash@50060400 {

	compatible = "st,stm32f756-hash";

	reg = <0x50060400 0x400>;

	interrupts = <80>;

	clocks = <&rcc 0 STM32F7_AHB2_CLOCK(HASH)>;

	resets = <&rcc STM32F7_AHB2_RESET(HASH)>;

	dmas = <&dma2 7 2 0x400 0x0>;

	dma-names = "in";

	dma-maxburst = <0>;
