Iuliana Prodan	87870cfb4b	crypto: caam - add support for cmac(aes) ... Add cmac(aes) keyed hash offloading support. Similar to xcbc implementation, driver must make sure there are still some bytes buffered when ahash_final() is called. This way HW is able to decide whether padding is needed and which key to derive (L -> K1 / K2) for the last block.

Iuliana Prodan	12b8567f6f	crypto: caam - add support for xcbc(aes) ... Add xcbc(aes) offloading support. Due to xcbc algorithm design and HW implementation in CAAM, driver must still have some bytes to send to the crypto engine when ahash_final() is called - such that HW correctly uses either K2 or K3 for the last block.
