Can you please test CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y too?  Implementations of
crypto algorithms shouldn't be enabled unless they are passing all tests.

Also, did you compare the performance of this hardware to ARMv8 CE?  I thought
that QCE (at least on other SoCs) isn't very useful because ARMv8 CE is faster.
