Now some cipher hardware engines prefer to handle bulk block rather than one
sector (512 bytes) created by dm-crypt, cause these cipher engines can handle
the intermediate values (IV) by themselves in one bulk block. This means we
can increase the size of the request by merging request rather than always 512
bytes and thus increase the hardware engine processing speed.

So introduce 'CRYPTO_ALG_BULK' flag to indicate this cipher can support bulk
mode.

Nack.  As I said before, please do it using explicit IV generators
like we do for IPsec.
