Imagination Technologies hardware hash accelerator

The hash accelerator provides hardware hashing acceleration for
SHA1, SHA224, SHA256 and MD5 hashes

Required properties:

- compatible : "img,hash-accelerator"
- reg : Offset and length of the register set for the module, and the DMA port
- interrupts : The designated IRQ line for the hashing module.
- dmas : DMA specifier as per Documentation/devicetree/bindings/dma/dma.txt
- dma-names : Should be "tx"
- clocks : Clock specifiers
- clock-names : "sys" Used to clock the hash block registers
		"hash" Used to clock data through the accelerator

Example:

	hash: hash@18149600 {
	compatible = "img,hash-accelerator";
		reg = <0x18149600 0x100>, <0x18101100 0x4>;
		interrupts = <GIC_SHARED 59 IRQ_TYPE_LEVEL_HIGH>;
		dmas = <&dma 8 0xffffffff 0>;
		dma-names = "tx";
		clocks = <&cr_periph SYS_CLK_HASH>, <&clk_periph PERIPH_CLK_ROM>;
		clock-names = "sys", "hash";
	};
