crypto: arm64 - convert to use crypto_simd_usable()
Replace all calls to may_use_simd() in the arm64 crypto code with crypto_simd_usable(), in order to allow testing the no-SIMD code paths. Signed-off-by: Eric Biggers <ebiggers@google.com> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
