crypto: qat - generate dynamically arbiter mappings

Browse Source 
The thread-to-arbiter mapping describes which arbiter can assign jobs
to an acceleration engine thread.
The existing mappings are functionally correct, but hardcoded and not
optimized.

Replace the static mappings with an algorithm that generates optimal
mappings, based on the loaded configuration.

The logic has been made common so that it can be shared between all
QAT GEN4 devices.
