[PATCH] s390: crypto: add select CRYPTO_AEAD for aes

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The aes driver registers both skcipher and aead algorithms,
but when aead is not enabled this causes a link failure:

s390-linux-ld: arch/s390/crypto/aes_s390.o: in function `aes_s390_fini':
arch/s390/crypto/aes_s390.c:969:(.text+0x115e): undefined reference to `crypto_unregister_aead'
s390-linux-ld: arch/s390/crypto/aes_s390.o: in function `aes_s390_init':
arch/s390/crypto/aes_s390.c:1028:(.init.text+0x294): undefined reference to `crypto_register_aead'

Add the missing 'select' statement.

Fixes: bf7fa038707c ("s390/crypto: add s390 platform specific aes gcm support.")
