[dts] [dts 7/9] Optimize VF devices creation and network devices pass-through function

[Yong Liu <yong.liu@intel.com>]

From: Marvin Liu <yong.liu@intel.com>

Add pt devices list in qemu_kvm module which can support devices free in
virtual scenario module.
Support netdevie object get by pci address.
