[RFC,v4,4/4] crypto: Add the CRYPTO_ALG_BULK flag for ecb(aes) cipher

Since the ecb(aes) cipher does not need to handle the IV things for encryption
or decryption, that means it can support for bulk block when handling data.
Thus this patch adds the CRYPTO_ALG_BULK flag for ecb(aes) cipher to improve
the hardware aes engine's efficiency.
