Nomap regions are treated as "reserved". When region boundaries are not
page aligned, we usually increase the "reserved" regions rather than
decrease them. So, we should use memblock_region_reserved_base_pfn()/
memblock_region_reserved_end_pfn() instead of memblock_region_memory_
base_pfn()/memblock_region_memory_base_pfn() to calculate boundaries.
