The Blackfin CRC driver was removed by commit 9678a8dc53 ("crypto:
bfin_crc - remove blackfin CRC driver"), but it was forgotten to remove
the corresponding "hmac(crc32)" test vectors. I see no point in keeping
them since nothing else appears to implement or use "hmac(crc32)", which
isn't an algorithm that makes sense anyway because HMAC is meant to be
used with a cryptographically secure hash function, which CRC's are not.
Thus, remove the unneeded test vectors.

The multi buffer concurrent requests ahash speed test only
supported the cycles mode. Add support for the so called
jiffies mode that test performance of bytes/sec.
We only add support for digest mode at the moment.

For multiple buffers speed tests, the number of buffers, or
requests, used actually sets the level of parallelism a tfm
provider may utilize to hide latency. The existing number
(of 8) is good for some software based providers but not
enough for many HW providers with deep FIFOs.
Add a module parameter that allows setting the number of
multiple buffers/requests used, leaving the default at 8.

The AEAD speed test pretended to support decryption, however that support
was broken as decryption requires a valid auth field which the test did
not provide.
Fix this by running the encryption path once with inout/output sgls
switched to calculate the auth field prior to performing decryption
speed tests.

The multi buffer ahash speed test was allocating multiple
buffers for use with the multiple outstanding requests
it was starting but never actually using them (except
to free them), instead using a different single statically
allocated buffer for all requests.
Fix this by actually using the allocated buffers for the test.
It is noted that it may seem tempting to instead remove the
allocation and free of the multiple buffers and leave things as
they are since this is a hash test where the input is read
only. However, after consideration I believe that multiple
buffers better reflect real life scenario with regard
to data cache and TLB behaviours etc.

The tcrypt AEAD cycles speed tests disables irqs during the test, which is
broken at the very least since commit
'1425d2d17f7309c6 ("crypto: tcrypt - Fix AEAD speed tests")'
adds a wait for completion as part of the test and probably since
switching to the new AEAD API.
While the result of taking a cycle count diff may not mean much on SMP
systems if the task migrates, it's good enough for tcrypt being the quick
& dirty dev tool it is. It's also what all the other (i.e. hash) cycle
speed tests do.

tcrypt is very tight-lipped when it succeeds, but a bit more feedback
would be useful when developing or debugging crypto drivers, especially
since even a successful run ends with the module failing to insert. Add
a couple of debug prints, which can be enabled with dynamic debug:
Before:
# insmod tcrypt.ko mode=10
insmod: can't insert 'tcrypt.ko': Resource temporarily unavailable
After:
# insmod tcrypt.ko mode=10 dyndbg
tcrypt: testing ecb(aes)
tcrypt: testing cbc(aes)
tcrypt: testing lrw(aes)
tcrypt: testing xts(aes)
tcrypt: testing ctr(aes)
