Realtek rsa accelerator present in RTS3915 IPCam processors.

Required properties:
- compatible: "realtek,rts3915-rsa"
- 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 two reset specifiers
- reset-names: identifier string for reset specifiers

Example:

	rsa: rsa@18f00000 {
		compatible = "realtek,rts3915-rsa";
		reg = <0x18f00000 0x10000>;
		interrupt-parent = <&cpuintc>;
		interrupts = <BSP_IRQ_ENCPY>;
		clocks = <&clks RLX_CLK_RSA>;
		clock-names = "rsa_ck";
		resets = <&reset FORCE_RESET_RSA>,
			<&sysmem SYS_MEM_SD_RSA>;
		reset-names = "rst", "sd";
		status = "disabled";
	};
