It turns out we can just modify the newer STM32 HASH driver
to be used with Ux500 and now that we have done that, delete
the old and sparsely maintained Ux500 HASH driver.

Commit d2825fa9365d ("crypto: sm3,sm4 - move into crypto directory") moves
the SM3 and SM4 stand-alone library and the algorithm implementation for
the Crypto API into the same directory, and the corresponding relationship
of Kconfig is modified, CONFIG_CRYPTO_SM3/4 corresponds to the stand-alone
library of SM3/4, and CONFIG_CRYPTO_SM3/4_GENERIC corresponds to the
algorithm implementation for the Crypto API. Therefore, it is necessary
for this module to depend on the correct algorithm.

Instead of doing manual queue management, let's use the crypto/engine
for that.
In the same time, rework the requests handling to be easier to
understand (and fix all bugs related to them).

The hardware does not handle 0 size length request, let's add a
fallback.
Furthermore fallback will be used for all unaligned case the hardware
cannot handle.

Move ARM- and ARM64-accelerated menus into a submenu under
the Crypto API menu (paralleling all the architectures).

Make each submenu always appear if the corresponding architecture
is supported. Get rid of the ARM_CRYPTO and ARM64_CRYPTO symbols.

The "ARM Accelerated" or "ARM64 Accelerated" entry disappears from:

Remove the CRYPTO_AES_ARM64 selection by the TI security

running make allmodconfig for arm (32-bit):

Hash and Crypto Engine (HACE) is designed to accelerate the
throughput of hash data digest, encryption, and decryption.

Basically, HACE can be divided into two independently engines
- Hash Engine and Crypto Engine. This patch aims to add HACE
hash engine driver for hash accelerator.

Various accelerated software implementation Kconfig values for S390 were
mistakenly placed into drivers/crypto/Kconfig, even though they're
mainly just SIMD code and live in arch/s390/crypto/ like usual. This
gives them the very unusual dependency on CRYPTO_HW, which leads to
problems elsewhere.

This patch fixes the issue by moving the Kconfig values for non-hardware
drivers into the usual place in crypto/Kconfig.

Implement a crypto library interface for the s390-native ChaCha20 cipher
algorithm. This allows us to stop to select CRYPTO_CHACHA20 and instead
select CRYPTO_ARCH_HAVE_LIB_CHACHA. This allows BIG_KEYS=y not to build
a whole ChaCha20 crypto infrastructure as a built-in, but build a smaller
CRYPTO_LIB_CHACHA instead.

Make CRYPTO_CHACHA_S390 config entry to look like similar ones on other
architectures. Remove CRYPTO_ALGAPI select as anyway it is selected by
CRYPTO_SKCIPHER.

Add a new test module and a test script for ChaCha20 cipher and its
interfaces. Here are test results on an idle z15 machine:
