This driver has never been hooked up in any board file, and cannot be
instantiated via device tree. I've been told that, at least on Tegra20,
the HW is slower at crypto than the main CPU. I have no test-case for
it. Hence, remove it.

Remove the old DCP driver as it had multiple severe issues. The driver
will be replaced by a more robust implementation. Here is a short list
of problems with this driver:

1) It only supports AES_CBC
2) The driver was apparently never ran behind anyone working with MXS. ie.:
   -> Restarting the DCP block is not done via mxs_reset_block()
   -> The DT name is not "fsl,dcp" or "fsl,mxs-dcp" as other MXS drivers
3) Introduces new ad-hoc IOCTLs
4) The IRQ handler can't use usual completion() in the driver because that'd
   trigger "scheduling while atomic" oops, yes?

- Updating Flag offsets so that they can be used for SHA256 and SHA512
- Adding the algo info.

This patch enables the DCP crypto functionality on imx28.
Currently, only aes-128-cbc is supported.
Moreover, the dcpboot misc-device, which is used by Freescale's
SDK tools and uses a non-software-readable OTP-key, is added.

Changes of v2:
- ring buffer for hardware-descriptors
- use of ablkcipher walk
- OTP key encryption/decryption via misc-device
  (compatible to Freescale-SDK)
- overall cleanup

The DCP is also capable of sha1/sha256 but I won't be able to add
that anytime soon.
Tested with built-in runtime-self-test, tcrypt and openssl via
cryptodev 1.6 on imx28-evk and a custom built imx28-board.

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.
