Use the new functions memory_region_init_{ram,rom,rom_device}()
instead of manually calling the _nomigrate() version and then
vmstate_register_ram_global().
Patch automatically created using coccinelle script:
spatch --in-place -sp_file scripts/coccinelle/memory-region-init-ram.cocci -dir hw
(As it turns out, there are no instances of the rom and
rom_device functions that are caught by this script.)
