Extent information can be helpful to the user to coordinate memory usage
with the external orchestrator and FM.
Expose the details of region extents by creating the following
sysfs entries.
/sys/bus/cxl/devices/dax_regionX/extentX.Y
/sys/bus/cxl/devices/dax_regionX/extentX.Y/offset
/sys/bus/cxl/devices/dax_regionX/extentX.Y/length
/sys/bus/cxl/devices/dax_regionX/extentX.Y/tag
