Paul Jackson 200001eb14 x86 boot: only pick up additional EFI memmap if add_efi_memmap flag 
Applies on top of the previous patch:
  x86 boot: add code to add BIOS provided EFI memory entries to kernel

Instead of always adding EFI memory map entries (if present) to the
memory map after initially finding either E820 BIOS memory map entries
and/or kernel command line memmap entries, -instead- only add such
additional EFI memory map entries if the kernel boot option:

    add_efi_memmap

is specified.

Requiring this 'add_efi_memmap' option is backward compatible with
kernels that didn't load such additional EFI memory map entries in
the first place, and it doesn't override a configuration that tries
to replace all E820 or EFI BIOS memory map entries with ones given
entirely on the kernel command line.
