Pull crypto updates from Herbert Xu:
 "API:
   - Add support for allocating transforms on a specific NUMA Node
   - Introduce the flag CRYPTO_ALG_ALLOCATES_MEMORY for storage users

  Algorithms:
   - Drop PMULL based ghash on arm64
   - Fixes for building with clang on x86
   - Add sha256 helper that does the digest in one go
   - Add SP800-56A rev 3 validation checks to dh

  Drivers:
   - Permit users to specify NUMA node in hisilicon/zip
   - Add support for i.MX6 in imx-rngc
   - Add sa2ul crypto driver
   - Add BA431 hwrng driver
   - Add Ingenic JZ4780 and X1000 hwrng driver
   - Spread IRQ affinity in inside-secure and marvell/cesa"
