    The new MACsec driver uses the AES crypto algorithm, but can be configured
    even if CONFIG_CRYPTO is disabled, leading to a build error:
    
    warning: (MAC80211 && MACSEC) selects CRYPTO_GCM which has unmet direct dependencies (CRYPTO)
    warning: (BT && CEPH_LIB && INET && MAC802154 && MAC80211 && BLK_DEV_RBD && MACSEC && AIRO_CS && LIBIPW && HOSTAP && USB_WUSB && RTLLIB_CRYPTO_CCMP && FS_ENCRYPTION && EXT4_ENCRYPTION && CEPH_FS && BIG_KEYS && ENCRYPTED_KEYS) selects CRYPTO_AES which has unmet direct dependencies (CRYPTO)
    crypto/built-in.o: In function `gcm_enc_copy_hash':
    aes_generic.c:(.text+0x2b8): undefined reference to `crypto_xor'
    aes_generic.c:(.text+0x2dc): undefined reference to `scatterwalk_map_and_copy'
    
    This adds an explicit 'select CRYPTO' statement the way that other
    drivers handle it.
