Currently, crypto4xx CFB and OFB AES ciphers are
failing testmgr's test vectors.
|cfb-aes-ppc4xx encryption overran dst buffer on test vector 3, cfg="in-place"
|ofb-aes-ppc4xx encryption overran dst buffer on test vector 1, cfg="in-place"
This is because of a very subtile "bug" in the hardware that
gets indirectly mentioned in 18.1.3.5 Encryption/Decryption
of the hardware spec:
the OFB and CFB modes for AES are listed there as operation
modes for >>> "Block ciphers" <<<. Which kind of makes sense,
but we would like them to be considered as stream ciphers just
like the CTR mode.
To workaround this issue and stop the hardware from causing
"overran dst buffer" on crypttexts that are not a multiple
of 16 (AES_BLOCK_SIZE), we force the driver to use the scatter
buffers as the go-between.
As a bonus this patch also kills redundant pd_uinfo->num_gd
and pd_uinfo->num_sd setters since the value has already been
set before.

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.
