057edc9c8b crypto: blake2s - move update and final logic to internal/blake2s.h 
Move most of blake2s_update() and blake2s_final() into new inline
functions __blake2s_update() and __blake2s_final() in
include/crypto/internal/blake2s.h so that this logic can be shared by
the shash helper functions.  This will avoid duplicating this logic
between the library and shash implementations.

66d7fb94e4 crypto: blake2s - generic C library implementation and selftest 
The C implementation was originally based on Samuel Neves' public
domain reference implementation but has since been heavily modified
for the kernel. We're able to do compile-time optimizations by moving
some scaffolding around the final function into the header file.

[ardb: - move from lib/zinc to lib/crypto
       - remove simd handling
       - rewrote selftest for better coverage
       - use fixed digest length for blake2s_hmac() and rename to
         blake2s256_hmac() ]
