basic hashes.

This patch adds support for the authenc(hmac(sha1),cbc(sm4)),
authenc(hmac(sm3),cbc(sm4)), authenc(hmac(sha1),rfc3686(ctr(sm4))),
and authenc(hmac(sm3),rfc3686(ctr(sm4))) aead ciphersuites.
These are necessary to support IPsec according to the Chinese standard
GM/T 022-1014 - IPsec VPN specification.
Note that there are no testvectors present in testmgr for these
ciphersuites. However, considering all building blocks have already been
verified elsewhere, it is fair to assume the generic implementation to be
correct-by-construction.
The hardware implementation has been fuzzed against this generic
implementation by means of a locally modified testmgr. The intention is
to upstream these testmgr changes but this is pending other testmgr changes
being made by Eric Biggers.
The patch has been tested with the eip197c_iewxkbc configuration on the
Xilinx VCU118 development board, using the abovementioned modified testmgr

This patch adds support for the Chacha20-Poly1305 cipher suite.
It adds both the basic rfc7539(chacha20,poly1305) as well as the
rfc7539esp(chacha20,poly1305) variant for IPsec ESP acceleration.
changes since v1:
- rebased on top of DES library changes done on cryptodev/master
- fixed crypto/Kconfig so that generic fallback is compiled as well
changes since v2:
- nothing
changes since v3:
- Fixed a problem where the tcrypt performance test would run fully on the
fallback cipher instead of the HW due to using an AAD length of 8 for
rfc7539esp. While this is not actually legal ESP (which includes SPI and
sequence number in the AAD as well), it is both inconvenient and not
necessary to run these vectors on the fallback cipher.
- Due to above, also realised that for plain (non-ESP) rfc7539, you
probably want to be able to run vectors with less than 8 bytes of AAD
on the HW, and this is actually possible as long as cryptlen is large
enough, so made that possible as well.

This removes some code determine which engine has which algorithms which
was effectively redundant (may have been forward-looking?) due to always
enabling all algorithms for all currently supported engines.
A future patch will use a different, more scalable approach to achieve
this. This is removed now because otherwise the next patch will add new
hardware which would otherwise have to be added to all algorithms, so
now is a convenient time to just get rid of this.

This patch fixes an issue with hash and HMAC operations that perform
"large" intermediate updates (i.e. combined size > 2 hash blocks) by
actually making use of the hardware's hash continue capabilities.
The original implementation would cache these updates in a buffer that
was 2 hash blocks in size and fail if all update calls combined would
overflow that buffer. Which caused the cryptomgr extra tests to fail.

This patch main goal is to improve driver performance by moving the
crypto request from a list to a RDR ring shadow.
This is possible since there is one producer and one consume for this
RDR request shadow and one ring descriptor is left unused.
Doing this change eliminates the use of spinlock when accessing the
descriptor ring and the need to dynamicaly allocate memory per crypto
request.
The crypto request is placed in the first RDR shadow descriptor only
if there are enough descriptors, when the result handler is invoked,
it fetches the first result descriptor from RDR shadow.
