Even if we do not register newly created RAM MemoryRegion for migration with
vmstate_register_ram_global() function, ram_save_live() still saves this region
to snapshot file with empty idstr=="". Consequently this results in error during
VM restoration in ram_load().
Register chipid_mem and rom_mem for migration to avoid this problem.
