crypto: arm64/sm4 - Fix wrong dependency of NEON/CE implementation

Commit d2825fa9 ("crypto: sm3,sm4 - move into crypto directory")
moved the sm4 library implementation from the lib/crypto directory to
the crypto directory and configured the name as CRYPTO_SM4. The arm64
SM4 NEON/CE implementation depends on this and needs to be modified
uniformly.
