Realtek HW Random Number Generator

Required properties:
- compatible: "realtek,rts3915-trng"
- reg: Offset and length of the register set for the block
- interrupts: The designated IRQ line for the block
- clocks: Clock specifiers
- clock-names: identifier string for clock specifiers
- resets: list of the reset specifiers
- reset-names: identifier string for reset specifiers

Example:

	trng: trng@188a0100 {
		compatible = "realtek,rts3915-trng";
		reg = <0x188a0100 0x100>;
		interrupt-parent = <&cpuintc>;
		interrupts = <BSP_IRQ_OTHERS>;
		clocks = <&clks RLX_CLK_TRNG>;
		clock-names = "trng_ck";
		resets = <&reset FORCE_RESET_TRNG>;
		reset-names = "rst";
		status = "disabled";
	};
