dt-bindings: rng: Convert stm32 RNG bindings to json-schema 



Convert the STM32 RNG binding to DT schema format using json-schema
Remove interrupt from the json-schema because it is not used by the driver.

STMicroelectronics STM32 HW RNG

===============================



The STM32 hardware random number generator is a simple fixed purpose IP and

is fully separated from other crypto functions.



Required properties:



- compatible : Should be "st,stm32-rng"

- reg : Should be register base and length as documented in the datasheet

- interrupts : The designated IRQ line for the RNG

- clocks : The clock needed to enable the RNG



Optional properties:

- resets : The reset to properly start RNG

- clock-error-detect : Enable the clock detection management



Example:



	rng: rng@50060800 {

		compatible = "st,stm32-rng";

		reg = <0x50060800 0x400>;

		interrupts = <80>;

		clocks = <&rcc 0 38>;

	};
