Pull crypto updates from Herbert Xu:
 "API:
   - Add the ability to abort a skcipher walk.

  Algorithms:
   - Fix XTS to actually do the stealing.
   - Add library helpers for AES and DES for single-block users.
   - Add library helpers for SHA256.
   - Add new DES key verification helper.
   - Add surrounding bits for ESSIV generator.
   - Add accelerations for aegis128.
   - Add test vectors for lzo-rle.

  Drivers:
   - Add i.MX8MQ support to caam.
   - Add gcm/ccm/cfb/ofb aes support in inside-secure.
   - Add ofb/cfb aes support in media-tek.
   - Add HiSilicon ZIP accelerator support.

  Others:
   - Fix potential race condition in padata.
   - Use unbound workqueues in padata"
