[dpdk-dev] [PATCH v4 13/70] crypto/qat: use contiguous allocation for DMA memory

[Anatoly Burakov]

All hardware drivers should allocate IOVA-contiguous
memzones for their hardware resources.

Also, remove the weird page alignment code.

Notes:
    v4:
    - Replace new API with new memzone flag
    
    v3:
    - Move the patch earlier in the patchset
    - Fix build system files to allow experimental API's
    - Removed non-sensical memzone flags code
