hw/arm/aspeed: don't make 'boot_rom' region 'nomigrate'
Currently we use memory_region_init_ram_nomigrate() to create
the "aspeed.boot_rom" memory region, and we don't manually
register it with vmstate_register_ram(). This currently
means that its contents are migrated but as a ram block
whose name is the empty string; in future it may mean they
are not migrated at all. Use memory_region_init_ram() instead.
Note that would be a cross-version migration compatibility break
for the "palmetto-bmc", "ast2500-evb" and "romulus-bmc" machines,
but migration is currently broken for them.
