efi: memmap: Move EFI fake memmap support into x86 arch tree
The EFI fake memmap support is specific to x86, which manipulates the
EFI memory map in various different ways after receiving it from the EFI
stub. On other architectures, we have managed to push back on this, and
the EFI memory map is kept pristine.
So let's move the fake memmap code into the x86 arch tree, where it
arguably belongs.
