Refactor the aegis128 code to get rid of indirect calls, and implement
SIMD versions of the init() and final() hooks. This results in a ~2x
speedup on ARM Cortex-A57 for ~1500 byte inputs.

Changes since v1:
- fix missing Sbox loads for plain SIMD on GCC
- fix endianness issue in final_simd() routine

Cc: Ondrej Mosnacek <omosnace@redhat.com>

Ard Biesheuvel (2):
  crypto: aegis128 - avoid function pointers for parameterization
  crypto: aegis128 - duplicate init() and final() hooks in SIMD code
