[dts] [PATCH 05/26] framework project_dpdk: asserting loading vfio-pci by using DPDK binding script

[Angela Czubak]

If one uses kernel with builtin modules lsmod does not print modules
even though they may be used. Thus, it is better to check if vfio-pci
can be bound by checking status with DPDK binding script (it appears in
unused drivers).
