Ard Biesheuvel 4d3f9d89c7 crypto: arm64/aes-ce-cipher - use AES library as fallback
Instead of calling into the table based scalar AES code in situations
where the SIMD unit may not be used, use the generic AES code, which
is more appropriate since it is less likely to be susceptible to
timing attacks.
