Realtek sha accelerator present in RTS3915 IPCam processors.

Required properties:
- compatible: "realtek,rts3915-sha"
- 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:

	sha: sha@19200000 {
		compatible = "realtek,rts3915-sha";
		reg = <0x19200000 0x10000>;
		interrupt-parent = <&cpuintc>;
		interrupts = <BSP_IRQ_ENCPY>;
		clocks = <&clks RLX_CLK_SHA>;
		clock-names = "sha_ck";
		resets = <&reset FORCE_RESET_SHA256>;
		reset-names = "rst";
		status = "disabled";
	};
