[PATCH] dt-bindings: rng: Convert stm32 RNG bindings to json-schema

[Benjamin Gaignard <benjamin.gaignard@st.com>]

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>;
-	};
