SEC v4.x were only 36-bit, SEC v5+ are 40-bit capable.
Also set a DMA mask for any job ring devices created.

In some device trees of previous version, there were string "fsl,sec4.0".
To be backward compatible with device trees, we have CAAM driver first
check "fsl,sec-v4.0", if it fails, then check for "fsl,sec4.0".

Access to the SEC4 DECOs (DEscriptor COntrollers) (for debug purposes)
isn't supported or used, and its register access initialization code
erroneously makes illegal i/o accesses that show up as errors when
run under simulation.  Remove it until proper support (via DECORR)
is added.

This patch converts the drivers in drivers/crypto/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

Help clarify that the number trailing in compatible nomenclature
is the version number of the device, i.e., change:

"fsl,p4080-sec4.0", "fsl,sec4.0";

to:

"fsl,p4080-sec-v4.0", "fsl,sec-v4.0";

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.
