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

* STMicroelectronics STM32 CRC

Required properties:

- compatible: Should be "st,stm32f7-crc".

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

- clocks: The input clock of the CRC instance

Optional properties: none

Example:

crc: crc@40023000 {

	compatible = "st,stm32f7-crc";

	reg = <0x40023000 0x400>;

	clocks = <&rcc 0 12>;

};
