Add support for Arm TrustZone CryptoCell 703.
The 703 is a variant of the CryptoCell 713 that supports only
algorithms certified by the Chinesse Office of the State Commercial
Cryptography Administration (OSCCA).

encapsulate set_cipher_mode call with another api,
preparation for specific hash behavior as needed in later patches
when SM3 introduced.

Adjust hash length such that it will not be fixed and general for all algs.
Instead make it suitable for certain context information.
This is preparation for SM3 support.

finup() operation was incorrect, padding was missing.
Fix by setting the ccree HW to enable padding.

Some ahash algorithms set .cra_type = &crypto_ahash_type. But this is
redundant with the C structure type ('struct ahash_alg'), and
crypto_register_ahash() already sets the .cra_type automatically.
Apparently the useless assignment has just been copy+pasted around.
So, remove the useless assignment from all the ahash algorithms.
This patch shouldn't change any actual behavior.

Many ahash algorithms set .cra_flags = CRYPTO_ALG_TYPE_AHASH. But this
is redundant with the C structure type ('struct ahash_alg'), and
crypto_register_ahash() already sets the type flag automatically,
clearing any type flag that was already there. Apparently the useless
assignment has just been copy+pasted around.
