Now that all "blkcipher" algorithms have been converted to "skcipher",
remove the blkcipher algorithm type.

The skcipher (symmetric key cipher) algorithm type was introduced a few
years ago to replace both blkcipher and ablkcipher (synchronous and
asynchronous block cipher).  The advantages of skcipher include:

  - A much less confusing name, since none of these algorithm types have
    ever actually been for raw block ciphers, but rather for all
    length-preserving encryption modes including block cipher modes of
    operation, stream ciphers, and other length-preserving modes.

  - It unified blkcipher and ablkcipher into a single algorithm type
    which supports both synchronous and asynchronous implementations.
    Note, blkcipher already operated only on scatterlists, so the fact
    that skcipher does too isn't a regression in functionality.

  - Better type safety by using struct skcipher_alg, struct
    crypto_skcipher, etc. instead of crypto_alg, crypto_tfm, etc.

  - It sometimes simplifies the implementations of algorithms.

Also, the blkcipher API was no longer being tested.

crypto_has_skcipher() and crypto_has_skcipher2() do the same thing: they
check for the availability of an algorithm of type skcipher, blkcipher,
or ablkcipher, which also meets any non-type constraints the caller
specified.  And they have exactly the same prototype.

Therefore, eliminate the redundancy by removing crypto_has_skcipher()
and renaming crypto_has_skcipher2() to crypto_has_skcipher().

Test vectors for blake2b with various digest sizes. As the algorithm is
the same up to the digest calculation, the key and input data length is
distributed in a way that tests all combinanions of the two over the
digest sizes.

Based on the suggestion from Eric, the following input sizes are tested
[0, 1, 7, 15, 64, 247, 256], where blake2b blocksize is 128, so the
padded and the non-padded input buffers are tested.

          blake2b-160  blake2b-256  blake2b-384  blake2b-512
         ---------------------------------------------------
len=0   | klen=0       klen=1       klen=32      klen=64
len=1   | klen=32      klen=64      klen=0       klen=1
len=7   | klen=64      klen=0       klen=1       klen=32
len=15  | klen=1       klen=32      klen=64      klen=0
len=64  | klen=0       klen=1       klen=32      klen=64
len=247 | klen=32      klen=64      klen=0       klen=1
len=256 | klen=64      klen=0       klen=1       klen=32

Where key:

- klen=0: empty key
- klen=1: 1 byte value 0x42, 'B'
- klen=32: first 32 bytes of the default key, sequence 00..1f
- klen=64: default key, sequence 00..3f

The unkeyed vectors are ordered before keyed, as this is required by
testmgr.

The patch brings support of several BLAKE2 variants (2b with various
digest lengths).  The keyed digest is supported, using tfm->setkey call.
The in-tree user will be btrfs (for checksumming), we're going to use
the BLAKE2b-256 variant.

The code is reference implementation taken from the official sources and
modified in terms of kernel coding style (whitespace, comments, uintXX_t
-> uXX types, removed unused prototypes and #ifdefs, removed testing
code, changed secure_zero_memory -> memzero_explicit, used own helpers
for unaligned reads/writes and rotations).

Further changes removed sanity checks of key length or output size,
these values are verified in the crypto API callbacks or hardcoded in

The elliptic curve arithmetic library used by the EC-DH KPP implementation
assumes big endian byte order, and unconditionally reverses the byte
and word order of multi-limb quantities. On big endian systems, the byte
reordering is not necessary, while the word ordering needs to be retained.

So replace the __swab64() invocation with a call to be64_to_cpu() which
should do the right thing for both little and big endian builds.

ccp_tx_submit is passed a dma_async_tx_descriptor which is contained in
a ccp_dma_desc and adds it to a ccp channel's pending list:

	list_del(&desc->entry);
	list_add_tail(&desc->entry, &chan->pending);

The problem is that desc->entry may be uninitialized in the
async_trigger_callback path where the descriptor was gotten
from ccp_prep_dma_interrupt which got it from ccp_alloc_dma_desc
which doesn't initialize the desc->entry list head. So, just
initialize the list head to avoid the problem.

Tiny fix to make QM/ZIP error callback print clear and right. If one version
hardware does not support error handling, we directly print this.

And QM is embedded in ZIP, we can use ZIP print only, so remove unnecessary
QM print.

SEV INIT command loads the SEV related persistent data from NVS
and initializes the platform context. The firmware validates the
persistent state. If validation fails, the firmware will reset
the persisent state and return an integrity check failure status.

At this point, a subsequent INIT command should succeed, so retry
the command. The INIT command retry is only done during driver
initialization.

Additional enums along with SEV_RET_SECURE_DATA_INVALID are added
to sev_ret_code to maintain continuity and relevance of enum values.
