crypto: sahara - Add driver for SAHARA2 accelerator.
SAHARA2 HW module is included in the i.MX27 SoC from Freescale. It is capable of performing cipher algorithms such as AES, 3DES..., hashing and RNG too. This driver provides support for AES-CBC and AES-ECB by now.

+Freescale SAHARA Cryptographic Accelerator included in some i.MX chips.
+Currently only i.MX27 is supported.
+
+Required properties:
+- compatible : Should be "fsl,<soc>-sahara"
+- reg : Should contain SAHARA registers location and length
+- interrupts : Should contain SAHARA interrupt number
+
+Example:
+
+sah@10025000 {
+ compatible = "fsl,imx27-sahara";
+ reg = < 0x10025000 0x800>;
+ interrupts = <75>;
+};
