Pavel Tatashin a9a9e77fbf mm: move mirrored memory specific code outside of memmap_init_zone 
memmap_init_zone, is getting complex, because it is called from different
contexts: hotplug, and during boot, and also because it must handle some
architecture quirks.  One of them is mirrored memory.

Move the code that decides whether to skip mirrored memory outside of
memmap_init_zone, into a separate function.
