Kim Phillips 4427b1b4ec 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.

Kim Phillips 8e8ec596e6 crypto: caam - Add support for the Freescale SEC4/CAAM
The SEC4 supercedes the SEC2.x/3.x as Freescale's
Integrated Security Engine.  Its programming model is
incompatible with all prior versions of the SEC (talitos).

The SEC4 is also known as the Cryptographic Accelerator
and Assurance Module (CAAM); this driver is named caam.

This initial submission does not include support for Data Path
mode operation - AEAD descriptors are submitted via the job
ring interface, while the Queue Interface (QI) is enabled
for use by others.  Only AEAD algorithms are implemented
at this time, for use with IPsec.

Many thanks to the Freescale STC team for their contributions
to this driver.
