Realign struct crypto_engine to reduce its size by 8 bytes. Total size
is now 192 bytes, allowing it to fit within 3 cachelines instead of 4.
pahole output before:
/* size: 200, cachelines: 4, members: 17 */
/* sum members: 183, holes: 3, sum holes: 17 */
/* paddings: 1, sum paddings: 4 */
/* last cacheline: 8 bytes */
and after:
/* size: 192, cachelines: 3, members: 17 */
/* sum members: 183, holes: 2, sum holes: 9 */
/* paddings: 1, sum paddings: 4 */
No functional changes intended.

Most drivers should not access the internal details of struct
crypto_engine. Move it into the internal header file.

Create crypto/internal/engine.h to house details that should not
be used by drivers. It is empty for the time being.
