mm/devm_memremap_pages: enable sub-section remap
Teach devm_memremap_pages() about the new sub-section capabilities of arch_{add,remove}_memory(). Effectively, just replace all usage of align_start, align_end, and align_size with res->start, res->end, and resource_size(res). The existing sanity check will still make sure that the two separate remap attempts do not collide within a sub-section (2MB on x86).
