Introduce a new crypto PMD for hardware accelerators based on UADK [1].
UADK is a framework for user applications to access hardware accelerators.
UADK relies on IOMMU SVA (Shared Virtual Address) feature, which share
the same page table between IOMMU and MMU.
Thereby user application can directly use virtual address for device dma,
which enhances the performance as well as easy usability.
This patch adds the basic framework.
[1] https://github.com/Linaro/uadk
Test:
sudo dpdk-test --vdev=crypto_uadk (--log-level=6)
RTE>>cryptodev_uadk_autotest
RTE>>quit
Remove this test info. It can be in your last patch where test app changes are
introduced.

I believe dirs is not required. You cannot assume that the lib is installed in
/usr/local/lib/.
Check other PMDs which have such dependencies. Eg. Ipsec-mb
Double checked,
This is workable via setting env for building.
export LIBRARY_PATH=/usr/local/lib
Thanks
