[v7,00/16] compress/qat: add compression PMD

Create compression PMD for Intel QuickAssist devices Currently only the C62x and c3xxx devices are supported.

The qat comp PMD supports
 - stateless compression and
   decompression using the Deflate algorithm with Fixed Huffman
   encoding. Dynamic huffman encoding is not supported, it
   will be added in a later patch.
 - checksum generation: Adler32, CRC32 and combined.

The compression service is hosted on a QuickAssist VF PCI device, which is managed by code in the drivers/common/qat directory.

v7 changes:
 - modified makefile to avoid compiling the PMD when no services are
   available (like in v5), but solving the build issue when libcrypto is
   not present
 - fixed meson build when libcrypto is not present
 - removed unnecessary unsupported feature list from .ini files
 - removed leftover Gerrit-Id tag
 - modified commit tile to have uppercase FW

v6 changes:
 - fixed makefile issue when cross compiling

v5 changes:
 - rebased against latest r/n and features/default.ini
 - fixed common/qat/Makefile so no build output files
   left hanging around in compress/qat src dir.

v4 changes:
 - corrected capabilities

v3 changes:
 - only commit message changes, i.e. removed ChangeId and fixed typos


v2 changes:
- Added check for correct firmware
- Split patchset
- Added documentation
- removed support for scatter-gather-lists and related config flag
- Removed support for Dynamic huffman encoding and related IM buffer config flag
- Removed support for DH895xcc device
