crypto: caam/qi - add GCM support
Add support for AES working in Galois Counter Mode. The following algorithms are added: gcm(aes) rfc4106(gcm(aes)) rfc4543(gcm(aes)) There is a limitation related to IV size, similar to the one present in SW implementation (crypto/gcm.c): The only IV size allowed is 12 bytes. It will be padded by HW to the right with 0x0000_0001 (up to 16 bytes - AES block size), according to the GCM specification.
