Allow sub-section sized ranges to be added to the memmap.
populate_section_memmap() takes an explict pfn range rather than
assuming a full section, and those parameters are plumbed all the way

current deployments. New warnings are added to clarify which memmap
allocation paths are sub-section capable.
