crypto: mxs - Add Freescale MXS DCP driver
Add support for the MXS DCP block. The driver currently supports SHA-1/SHA-256 hashing and AES-128 CBC/ECB modes. The non-standard CRC32 is not yet supported.

+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";
+};
