dm: vPCI: add assign/deassign PCI device IC APIs

Browse Source 
Add assign/deassign PCI device ioctl APIs assign a PCI device from SOS to
post-launched VM or deassign a PCI device from post-launched VM to SOS. This patch
is prepared for spliting passthrough PCI device from DM to HV.
The old assign/deassign ptdev APIs will be discarded.
