VF's drivers can't modify GGTT PTEs except the range explicitly assigned by the PF driver. To allow hardware enforcement of this requirement, each GGTT PTE has a field with the VF number that identifies which VF can modify that particular GGTT PTE entry. Only PF driver can modify this field and PF driver shall do that before VF drivers will be loaded. Add function to prepare PTEs. Since it will be used only by the PF driver, make it available only for CONFIG_PCI_IOV=y.
