Pull crypto updates from Herbert Xu:
 "API:
   - Allow DRBG testing through user-space af_alg
   - Add tcrypt speed testing support for keyed hashes
   - Add type-safe init/exit hooks for ahash

  Algorithms:
   - Mark arc4 as obsolete and pending for future removal
   - Mark anubis, khazad, sead and tea as obsolete
   - Improve boot-time xor benchmark
   - Add OSCCA SM2 asymmetric cipher algorithm and use it for integrity

  Drivers:
   - Fixes and enhancement for XTS in caam
   - Add support for XIP8001B hwrng in xiphera-trng
   - Add RNG and hash support in sun8i-ce/sun8i-ss
   - Allow imx-rngc to be used by kernel entropy pool
   - Use crypto engine in omap-sham
   - Add support for Ingenic X1830 with ingenic"
