Ard Biesheuvel ec59a65d69 crypto: arm64/sha2-ce - prevent asm code finalization in final() path
Ensure that the asm code finalization path is not triggered when
invoked via final(), since it already takes care of that itself.

Ard Biesheuvel 03802f6a80 crypto: arm64/sha2-ce - move SHA-224/256 ARMv8 implementation to base layer
This removes all the boilerplate from the existing implementation,
and replaces it with calls into the base layer.

Colin Ian King 031cb42838 arm64/crypto: remove redundant update of data
Originally found by cppcheck:

[arch/arm64/crypto/sha2-ce-glue.c:153]: (warning) Assignment of
  function parameter has no effect outside the function. Did you
  forget dereferencing it?

Updating data by blocks * SHA256_BLOCK_SIZE at the end of
sha2_finup is redundant code and can be removed.
