[PATCH v2 -next] crypto: atmel - Fix build error of CRYPTO_AUTHENC

[YueHaibing]

If CRYPTO_DEV_ATMEL_AUTHENC is m, CRYPTO_DEV_ATMEL_SHA is m,
but CRYPTO_DEV_ATMEL_AES is y, building will fails:

drivers/crypto/atmel-aes.o: In function `atmel_aes_authenc_init_tfm':
atmel-aes.c:(.text+0x670): undefined reference to `atmel_sha_authenc_get_reqsize'
atmel-aes.c:(.text+0x67a): undefined reference to `atmel_sha_authenc_spawn'
drivers/crypto/atmel-aes.o: In function `atmel_aes_authenc_setkey':
atmel-aes.c:(.text+0x7e5): undefined reference to `atmel_sha_authenc_setkey'

Make CRYPTO_DEV_ATMEL_AUTHENC depends on CRYPTO_DEV_ATMEL_AES,
and select CRYPTO_DEV_ATMEL_SHA and CRYPTO_AUTHENC for it under there.
