mm: mark early-init static variables with __meminitdata
Static variables defined inside __meminit functions should also be marked
with __meminitdata, so that their storage is placed in the .init.data
section and reclaimed with free_initmem(), thereby reducing permanent .bss
memory usage when CONFIG_MEMORY_HOTPLUG is disabled.
