dpdk: Add PMD type for Cavium LiquidIO II CN23XX

1、Adding PMD type for support Cavium LiquidIO II CN23XX NIC;
2、Our company is using VPP + DPDK +Cavium LiquidIO II CN23XX NIC,
Unfortunately, the latest VPP code does not support
Cavium LiquidIO II CN23XX pci.
So I increased the PMD type to support LiquidIO NIC,
and can run normally, we most subsequent projects are
based on VPP + DPDK + Cavium LiquidIO II CN23XX NIC model,
so I hope VPP team can adopt this requirement, thanks a lot.
