crypto: mxs - Add Freescale MXS DCP driver

Freescale DCP (Data Co-Processor) found on i.MX23/i.MX28 .

Required properties:

- compatible : Should be "fsl,<soc>-dcp"

- reg : Should contain MXS DCP registers location and length

- interrupts : Should contain MXS DCP interrupt numbers, VMI IRQ and DCP IRQ

               must be supplied, optionally Secure IRQ can be present, but

	       is currently not implemented and not used.

Example:

dcp@80028000 {

	compatible = "fsl,imx28-dcp", "fsl,imx23-dcp";

	reg = <0x80028000 0x2000>;

	interrupts = <52 53>;

	status = "okay";

};

	source "drivers/crypto/ccp/Kconfig"

endif

	  The Freescale i.MX23/i.MX28 has SHA1/SHA256 and AES128 CBC/ECB

	  co-processor on the die.

	  To compile this driver as a module, choose M here: the module

	  will be called mxs-dcp.
