The SEC Job Rings are now available as individual devices.
This would enable sharing of job rings between kernel and
user space. Job Rings can now be dynamically bound/unbound
from kernel.

Changes are made in the following layers of CAAM Driver
1. Controller driver
        - Does basic initialization of CAAM Block.
        - Creates platform devices for Job Rings.
(Earlier the initialization of Job ring  was done
 by the controller driver)

2. JobRing Platform driver
        - Manages the platform Job Ring devices created
          by the controller driver

This patch adds an option to the Kconfig file for
SEC which enables the user to see the debug messages
that are printed inside the SEC driver.

caam_read copies random bytes from two buffers into output.

caam rng can fill empty buffer 0xffff bytes at a time,
but the buffer sizes are rounded down to multiple of cacheline size.

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.
