hv: vpci: an assign PT device should support FLR or PM reset

Browse Source 
Before we assign a PT device to post-launched VM, we should reset the PCI device
first. However, ACRN hypervisor doesn't plan to support PCIe hot-plug and doesn't
support PCIe bridge Secondary Bus Reset. So the PT device must support FLR or PM
reset. This patch do this check when assigning a PT device to post-launched VM.
