- add IRQF_SHARED to request_irq flags to support parts such as
the p1023 that has one IRQ line per couple of rings.

- resetting a job ring triggers an interrupt, so move request_irq
prior to jr_reset to avoid 'got IRQ but nobody cared' messages.

- disable IRQs in h/w to avoid contention between reset and
interrupt status

- delete invalid comment - if there were incomplete jobs,
module would be in use, preventing an unload.

This patch fixes 2 hmac inter-dependent bugs.

1. "omap-sham: hash-in-progress is stored in hw format" commit introduced
optimization where temporary hash had been stored in OMAP specific format
(big endian).
For SHA1 it is different to real hash format, which is little endian.
Final HMAC value was calculated using incorrect hash.
Because CONFIG_CRYPTO_MANAGER_TESTS was disabled this error remained
unnoticed. After enabling this option, bug has been found.

2. HMAC was calculated using temporrary hash value.
For a single-request updates, temporary hash was the final one and
HMAC result was correct. But in fact only the final hash had to be used.
All crypto tests for HMAC produces only single request and
could not catch the problem. This problem is fixed here.

The SPAcc's have 2 equally sized FIFO's - a command FIFO and a status
FIFO.  The command FIFO takes the requests that are to be performed and
the status FIFO reports the results.  It is possible to get into the
situation where there are more free spaces in the command FIFO than the
status FIFO if we don't empty the status FIFO quickly enough resulting
in a possible overflow of the status FIFO.  This can result in incorrect
status being reported in the status FIFO.

Make sure that when we are submitting requests the number of requests
that have been dispatched but not yet popped from the status FIFO does
not exceed the size of a single FIFO.

Add new SHA-1/256 module that never needs any fallback and just calls the
PadLock hardware instruction supported from VIA Nano processors to implement
the "update" and "final" function.

They are respectively named "sha1_alg_nano" and "sha256_alg_nano", and will
be used on any VIA Nano processor or the later ones. On VIA C7 CPU, the
"sha1_alg" and "sha256_alg" modules will still be used as before.

- all the integration parameters have been captured by the binding.
- the block name really uniquely identifies this hardware.

Some advocate putting SoC names everywhere in case software needs
to work around some chip-specific bug, but more precise SoC
information already exists in SVR, and board information already
exists in the top-level device tree node.

Note that sometimes the SoC name is a worse identifier than the
block version, as the block version can change between revisions
of the same SoC.

As a matter of historical reference, neither SEC versions 2.x
nor 3.x (driven by talitos) ever needed CHIP references.

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.
