Christian Lamparter 25baaf8e2c crypto: crypto4xx - fix ctr-aes missing output IV 
Commit 8efd972ef9 ("crypto: testmgr - support checking skcipher output IV")
caused the crypto4xx driver to produce the following error:

| ctr-aes-ppc4xx encryption test failed (wrong output IV)
| on test vector 0, cfg="in-place"

This patch fixes this by reworking the crypto4xx_setkey_aes()
function to:

 - not save the iv for ECB (as per 18.2.38 CRYP0_SA_CMD_0:
   "This bit mut be cleared for DES ECB mode or AES ECB mode,
   when no IV is used.")

 - instruct the hardware to save the generated IV for all
   other modes of operations that have IV and then supply
   it back to the callee in pretty much the same way as we
   do it for cbc-aes already.

 - make it clear that the DIR_(IN|OUT)BOUND is the important
   bit that tells the hardware to encrypt or decrypt the data.
   (this is cosmetic - but it hopefully prevents me from
    getting confused again).

 - don't load any bogus hash when we don't use any hash
   operation to begin with.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
