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" ]
