hv: PTM: Create virtual root port

Browse Source 
Create virtual root port through add_vdev hypercall. add_vdev
identifies the virtual device to add by its vendor id and device id, then
call the corresponding function to create virtual device.

	-create_vrp(): Find the right virtual root port to create
by its secondary bus number, then initialize the virtual root port.
And finally initialize PTM related configurations.

	-destroy_vrp(): nothing to destroy
