The call to sha256() occurs in code that is built when either
CRYPTO_AES_ARM64_CE_BLK or CRYPTO_AES_ARM64_NEON_BLK. The option
CRYPTO_AES_ARM64 is unrelated, notwithstanding its documentation. I'll
be removing CRYPTO_AES_ARM64 soon anyway, but before doing that, fix
where CRYPTO_LIB_SHA256 is selected from.
Fixes: 01834444d972 ("crypto: arm64/aes - use SHA-256 library instead of
crypto_shash")
