nvdimm: set non-volatile on the memory region
qemu-system-x86_64 -machine pc,nvdimm -m 2G,slots=4,maxmem=16G -enable-kvm -monitor stdio -object memory-backend-file,id=mem1,share=on,mem-path=/tmp/foo,size=1G -device nvdimm,id=nvdimm1,memdev=mem1
HMP info mtree command reflects the flag with "nv-" prefix on memory type:
(qemu) info mtree
0000000100000000-000000013fffffff (prio 0, nv-i/o): alias nvdimm-memory @/objects/mem1 0000000000000000-000000003fffffff
(qemu) info mtree -f
0000000100000000-000000013fffffff (prio 0, nv-ram): /objects/mem1
