Dan Williams 88e9a5b796 efi/fake_mem: arrange for a resource entry per efi_fake_mem instance
In preparation for attaching a platform device per iomem resource teach
the efi_fake_mem code to create an e820 entry per instance.  Similar to
E820_TYPE_PRAM, bypass merging resource when the e820 map is sanitized.
