crypto: qat - expose deflate through acomp api for QAT GEN2
Add infrastructure for implementing the acomp APIs in the QAT driver and
expose the deflate algorithm for QAT GEN2 devices.
This adds
(1) the compression service which includes logic to create, allocate
and handle compression instances;
(2) logic to create configuration entries at probe time for the
compression instances;
(3) updates to the firmware API for allowing the compression service;
and;
(4) a back-end for deflate that implements the acomp api for QAT GEN2
devices.
The implementation configures the device to produce data compressed
statically, optimized for throughput over compression ratio.
