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.

Accelerator and Assurance Module (CAAM).
=====================================================================
Overview
DESCRIPTION
SEC 4 h/w can process requests from 2 types of sources.
1. DPAA Queue Interface (HW interface between Queue Manager & SEC 4).
2. Job Rings (HW interface between cores & SEC 4 registers).
High Speed Data Path Configuration:
HW interface between QM & SEC 4 and also BM & SEC 4, on DPAA-enabled parts
such as the P4080. The number of simultaneous dequeues the QI can make is
equal to the number of Descriptor Controller (DECO) engines in a particular
SEC version. E.g., the SEC 4.0 in the P4080 has 5 DECOs and can thus
dequeue from 5 subportals simultaneously.
Job Ring Data Path Configuration:
Each JR is located on a separate 4k page, they may (or may not) be made visible
in the memory partition devoted to a particular core. The P4080 has 4 JRs, so
up to 4 JRs can be configured; and all 4 JRs process requests in parallel.
=====================================================================
P4080 SEC 4 Node
Description
Node defines the base address of the SEC 4 block.
This block specifies the address range of all global
configuration registers for the SEC 4 block. It
also receives interrupts from the Run Time Integrity Check
(RTIC) function within the SEC 4 block.

/*
* Architecture-specific register access methods
*
* CAAM's bus-addressable registers are 64 bits internally.
* They have been wired to be safely accessible on 32-bit
* architectures, however. Registers were organized such
* that (a) they can be contained in 32 bits, (b) if not, then they
* can be treated as two 32-bit entities, or finally (c) if they
* must be treated as a single 64-bit value, then this can safely
* be done with two 32-bit cycles.
*
* For 32-bit operations on 64-bit values, CAAM follows the same
* 64-bit register access conventions as it's predecessors, in that
* writes are "triggered" by a write to the register at the numerically
* higher address, thus, a full 64-bit write cycle requires a write
* to the lower address, followed by a write to the higher address,
* which will latch/execute the write cycle.
*
* For example, let's assume a SW reset of CAAM through the master
* configuration register.
* - SWRST is in bit 31 of MCFG.
* - MCFG begins at base+0x0000.
* - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower)
* - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher)
*
* (and on Power, the convention is 0-31, 32-63, I know...)
*
* Assuming a 64-bit write to this MCFG to perform a software reset
* would then require a write of 0 to base+0x0000, followed by a
* write of 0x80000000 to base+0x0004, which would "execute" the
* reset.
*
* Of course, since MCFG 63-32 is all zero, we could cheat and simply
* write 0x8000000 to base+0x0004, and the reset would work fine.
* However, since CAAM does contain some write-and-read-intended
* 64-bit registers, this code defines 64-bit access methods for
* the sake of internal consistency and simplicity, and so that a
* clean transition to 64-bit is possible when it becomes necessary.
*
* There are limitations to this that the developer must recognize.
* 32-bit architectures cannot enforce an atomic-64 operation,
* Therefore:
*
* - On writes, since the HW is assumed to latch the cycle on the
* write of the higher-numeric-address word, then ordered
* writes work OK.
*
* - For reads, where a register contains a relevant value of more
* that 32 bits, the hardware employs logic to latch the other
* "half" of the data until read, ensuring an accurate value.
* This is of particular relevance when dealing with CAAM's
* performance counters.
