[dts] [PATCH V2] tests/virtio_event_idx_interrupt: optimize the code

[Wei Ling <weix.ling@intel.com>]

v1:
Add bind_dev parameter to replace restore_interfaces in start_vm
method to decide bind the NIC port to dpdk in vm or not.

v2:
Add set_target parameter because this suite no need build dpdk in vm.
