[Impact]
This set improves the error recovery flows in the QAT drivers and
adds a mechanism to test it through an heartbeat simulator.
This is an upstream patch set applied to linux-next and scheduled for 6.9.
Link to the upstream submission:
https://patchwork.kernel.org/project/linux-crypto/cover/20240202105324.50391-1-mun.chun.yep@intel.com/
We should apply this set to the Noble 6.8 kernel,
in order to experience less issues with qat and improve maintainability.
An added commit is required to update the configuration.
[Test case]
Unload and reload the module to verify that qat recover
and log issues properly. Use the added error injection mechanism
to verify the recovery flow.
[Fix]
Apply the following commits (from linux-next):

[Regression potential]
We may experience qat regression when crashing or restarting the module.
