[PATCH 2/4] crypto: caam - fix decryption shared vs. non-shared key setting

Key sharing is enabled by default in the shared descriptor. Using CBC decrypt, AES has to alter the key in order to decrypt. During high traffic decryption rates, i.e, when sharing starts to take place, we need to use a different OPERATION option to tell AES that the key was already altered by

[PATCH 4/4] crypto: caam - add support for sha512 variants of existing AEAD algorithms

In doing so, sha512 sized keys would not fit with the current descriptor inlining mechanism, so we now calculate whether keys should be referenced instead by pointers in the shared descriptor. also, use symbols for descriptor text lengths, and, ahem, unmap and free key i/o memory in cra_exit.
