Now that even DPDK 16.11 (LTS) reaches its end of life in November 2018, we can surely drop support for DPDK versions older than that. The PCI code will go through a major refactor soon, so this patch cleans it up first. Since this is the very first SPDK patch that drops support for older DPDK versions, it also introduces an #error directive that'll directly fail the build if the used DPDK lib is too old.
