    x86, e820, pci: reserve extra free space near end of RAM

    The point is to take all RAM resources we have, and
    _after_ we've added all the resources we've seen in
    the E820 tree, we then _also_ try to add fake reserved
    entries for any "round up to X" at the end of the RAM
    resources.

    [ Impact: improve PCI mem-resource allocation robustness, protect "stolen RAM" ]
