The existing e820-type-12 to pmem setup is converted to an nvdimm_bus that emits an nd_namespace_io device. Note that the X in 'pmemX' is now derived from the parent region. This provides some stability to the pmem devices names from boot-to-boot. The minor numbers are also more predictable by passing 0 to alloc_disk().
