Bug description:
  [Impact]
  We have several crypto accelerators for Hisilicon 1620 but unfortunately one 
of them is not mature and causes stress-ng tests failure. Disabling hisi_sec2 
makes kernel to run crypto functions without accelerator.

  [Fix]
  Disable CONFIG_CRYPTO_DEV_HISI_SEC2 temporarily until we have proper driver.

  [Test]
  $ sudo stress-ng --aggressive --verify --timeout 330 --metrics-brief --tz 
--times --af-alg 0
  $ echo $?

  [Regression Potential]
  This driver is only loaded on Hisilicon Hi1620 machines. Low risk for other 
platform.

  ==================================
  [Bug Description]
  CPU stress test fails with focal kernel

  [Steps to Reproduce]
  1) sudo apt-add-repository -y ppa:firmware-testing-team/ppa-fwts-stable
  2) sudo apt-add-repository -y ppa:hardware-certification/public
  3) sudo apt install -y canonical-certification-server
  4) Install focal kernel debs from https://launchpad.net/ubuntu/+source/linux
  5) Run CPU stress test with `sudo certify-advanced`

  [Actual Results]
  Failed with
  stress-ng: fail:  [6118] stress-ng-af-alg: bind failed, errno=19 (No such 
device)

  [Expected Results]
  Passed

  [Reproducibility]
  100%

  [Additional information]
  Same test with bionic-update kernel passed
