crypto: qat - enable deflate for QAT GEN4

Enable deflate for QAT GEN4 devices.

This adds
  (1) logic to create configuration entries at probe time for the
  compression instances for QAT GEN4 devices;
  (2) the implementation of QAT GEN4 specific compression operations,
  required since the creation of the compression request template is
  different between GEN2 and GEN4; and
  (3) updates to the firmware API related to compression for GEN4.

The implementation configures the device to produce data compressed
dynamically, optimized for throughput over compression ratio.
