In order to speed up aegis128 processing even more, duplicate the init()
and final() routines as SIMD versions in their entirety. This results
in a 2x speedup on ARM Cortex-A57 for ~1500 byte packets (using AES
instructions).

Instead of passing around an ops structure with function pointers,
which forces indirect calls to be used, refactor the code slightly
so we can use ordinary function calls. At the same time, switch to
a static key to decide whether or not the SIMD code path may be used.

crypto/aegis.h:27:32: warning:
crypto_aegis_const defined but not used [-Wunused-const-variable=]
crypto_aegis_const is only used in aegis128-core.c,
just move the definition over there.

Add some plumbing to allow the AEGIS128 code to be built with SIMD
routines for acceleration.

This reverts commit 3cd22a9ca7fcacfa00025ecf925c8a0121c7cc92
("crypto: aegis128 - provide a SIMD implementation based on NEON
intrinsics") and commit 467920a4b6c1cc41fdd55776be2d4a74d9d10469
("crypto: aegis128 - add support for SIMD acceleration").
They cause compile errors on platforms other than ARM because
the mechanism to selectively compile the SIMD code is broken.
