Changes from v1 [1]:
 - Fixed a bug where the guest might touch pmem region prior to the
   backing file being mapped into the guest's address space.

These patches add support to virtio-pmem to allow the pmem region to be
specified in either guest absolute terms or as a PCI BAR-relative address.
This is required to support virtio-pmem in Hyper-V, since Hyper-V only
allows PCI devices to operate on PCI memory ranges defined via BARs.

  virtio-pmem: Set DRIVER_OK status prior to creating pmem region
