Revert "crypto: aegis128 - add support for SIMD acceleration"
This reverts commit ecc8bc81f2fb3976737ef312f824ba6053aa3590 ("crypto: aegis128 - provide a SIMD implementation based on NEON intrinsics") and commit 7cdc0ddbf74a19cecb2f0e9efa2cae9d3c665189 ("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.
