Fix enum warnings in qat

2024-07-31T19:31:55+00:00

This fixes a number of clang 19 warnings:

    sys/dev/qat/qat_api/common/compression/dc_session.c:154:15: error: comparison of different enumeration types ('enum _CpaBoolean' and 'icp_qat_hw_compression_delayed_match_t') [-Werror,-Wenum-compare]
      154 |         if (CPA_TRUE == pService->comp_device_data.enableDmm) {
          |             ~~~~~~~~ ^  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    sys/dev/qat/qat_api/common/compression/dc_session.c:285:17: error: comparison of different enumeration types ('enum _CpaBoolean' and 'icp_qat_hw_compression_delayed_match_t') [-Werror,-Wenum-compare]
      285 |                     (CPA_TRUE == pService->comp_device_data.enableDmm) ?
          |                      ~~~~~~~~ ^  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The `enableDmm` field of variable `comp_device_data` is of type
`icp_qat_hw_compression_delayed_match_t`, not `CpaBoolean`. In this
case, we can seamlessly replace the value with
`ICP_QAT_HW_COMPRESSION_DELAYED_MATCH_ENABLED`, which is numerically
equal to `CPA_TRUE`.

acceleration for offloading security, authentication and compression
services from the CPU, thus significantly increasing the performance and
efficiency of standard platform solutions.

This commit introduces:
- Intel® 4xxx Series platform support.
- QuickAssist kernel API implementation update for Generation 4 device.
  Enabled services: symmetric cryptography and data compression.
- Increased default number of crypto instances in static configuration
  for performance purposes.

OCF backend changes:
- changed GCM/CCM MAC validation policy to generate MAC by HW
  and validate by SW due to the QAT HW limitations.
