Marvell Cryptographic Engines And Security Accelerator

Required properties:
- compatible: should be one of the following string
	      "marvell,orion-crypto"
	      "marvell,kirkwood-crypto"
	      "marvell,dove-crypto"
- reg: base physical address of the engine and length of memory mapped
       region. Can also contain an entry for the SRAM attached to the CESA,
       but this representation is deprecated and marvell,crypto-srams should
       be used instead
- reg-names: "regs". Can contain an "sram" entry, but this representation
	     is deprecated and marvell,crypto-srams should be used instead
- interrupts: interrupt number
- clocks: reference to the crypto engines clocks. This property is only
	  required for Dove platforms
- marvell,crypto-srams: phandle to crypto SRAM definitions

Optional properties:
- marvell,crypto-sram-size: SRAM size reserved for crypto operations, if not
			    specified the whole SRAM is used (2KB)

Examples:

	crypto@30000 {
		compatible = "marvell,orion-crypto";
		reg = <0x30000 0x10000>;
		reg-names = "regs";
		interrupts = <22>;
		marvell,crypto-srams = <&crypto_sram>;
		marvell,crypto-sram-size = <0x600>;
		status = "okay";
	};
