x86, mirror: x86 enabling - find mirrored memory ranges
UEFI GetMemoryMap() uses a new attribute bit to mark mirrored memory
address ranges. See UEFI 2.5 spec pages 157-158:
http://www.uefi.org/sites/default/files/resources/UEFI%202_5.pdf
On EFI enabled systems scan the memory map and tell memblock about any
mirrored ranges.
