Pull crypto updates from Herbert Xu:
"API:
- Fix dcache flushing crash in skcipher.
- Add hash finup self-tests.
- Reschedule during speed tests.
Algorithms:
- Remove insecure vmac and replace it with vmac64.
- Add public key verification for DH/ECDH.
Drivers:
- Decrease priority of sha-mb on x86.
- Improve NEON latency/throughput on ARM64.
- Add md5/sha384/sha512/des/3des to inside-secure.
- Support eip197d in inside-secure.
- Only register algorithms supported by the host in virtio.
- Add cts and remove incompatible cts1 from ccree.
- Add hisilicon SEC security accelerator driver.
- Replace msm hwrng driver with qcom pseudo rng driver.
Misc:
- Centralize CRC polynomials"
