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.

This patch is dependent on the cryptodev API patch re Huffman Encoding capability
https://patches.dpdk.org/patch/42286/

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
