Hemant Agrawal 83087a92e2 crypto/dpaa2_sec: support AES-CMAC integrity check
This patch adds support for AES_CMAC integrity in non-security mode.
This patch modifies the camm flib to handles the AES CMAC
without conflicting the proto ALG operations. i.e. by creating
another ALG operation routine.

/**
* DOC: About
*
* RTA (Runtime Assembler) Library is an easy and flexible runtime method for
* writing SEC descriptors. It implements a thin abstraction layer above
* SEC commands set; the resulting code is compact and similar to a
* descriptor sequence.
*
* RTA library improves comprehension of the SEC code, adds flexibility for
* writing complex descriptors and keeps the code lightweight. Should be used
* by whom needs to encode descriptors at runtime, with comprehensible flow
* control in descriptor.
*/
/**
* DOC: Usage
*
* RTA is used in kernel space by the SEC / CAAM (Cryptographic Acceleration and
* Assurance Module) kernel module (drivers/crypto/caam) and SEC / CAAM QI
* kernel module (Freescale QorIQ SDK).
*
* RTA is used in user space by USDPAA - User Space DataPath Acceleration
* Architecture (Freescale QorIQ SDK).
