Re-use vector processing stubs in ixgbe PMD defined for PPC for RISC-V.
This enables ixgbe PMD usage in scalar mode on this architecture.
The ixgbe PMD driver was validated with Intel X520-DA2 NIC and the
test-pmd application. Packet transfer checked using all UIO drivers
available for non-IOMMU platforms: uio_pci_generic, vfio-pci noiommu and
igb_uio.
