[PATCH v1] bbdev: add new operation for FFT processing

[Nicolas Chautru]

Hi, 
This contributions adds a new operation type to the existing ones
already supported by the bbdev PMDs.
This set of operation is FFT-based processing for 5GNR baseband
processing acceleration. This operates in the same lookaside fashion
as other existing bbdev operation with a dedicated set of capabilities
and parameters (marked as experimental).

I plan to also include a new PMD supporting this operation (and most of
the related capabilities) in the next couple of months (either in 22.06 
or 22.09) as well as extending the related bbdev-test.

I can update the release notes for 22.06 on subsequent patch vs or separate
commit (not there yet). Thanks for review feedback.
