Tested on QEMU with fs-dax and device-dax as vNVDIMM backends
respectively with vfio passthrough. The fs-dax case fails QEM

Add support to create the Xen mode namespace which turns the underlying
pfn device into PFN_MODE_XEN.

Xen hypervisor does not include NVDIMM driver and relies on the driver
in Dom0 Linux to probe pfn devices in PFN_MODE_XEN. Whenever such a pfn
device is probed, Dom0 Linux reports pages of the entire device, its
reserved area and data area to Xen hypervisor.
Signed-off-by: Haozhong Zhang
pfn device in PFN_MODE_XEN reserves an area for Xen hypervisor to place
its own pmem management data structures (i.e. frame table and M2P
table). The reserved area is not used and not mapped by Linux kernel,
and only the data area is mapped.
