Pull crypto updates from Herbert Xu:
 "API:
   - Add virtual-address based lskcipher interface
   - Optimise ahash/shash performance in light of costly indirect calls
   - Remove ahash alignmask attribute

  Algorithms:
   - Improve AES/XTS performance of 6-way unrolling for ppc
   - Remove some uses of obsolete algorithms (md4, md5, sha1)
   - Add FIPS 202 SHA-3 support in pkcs1pad
   - Add fast path for single-page messages in adiantum
   - Remove zlib-deflate

  Drivers:
   - Add support for S4 in meson RNG driver
   - Add STM32MP13x support in stm32
   - Add hwrng interface support in qcom-rng
   - Add support for deflate algorithm in hisilicon/zip"
