bootmem: Replace work_with_active_regions() with for_each_mem_pfn_range()
Callback based iteration is cumbersome and much less useful than
for_each_*() iterator. This patch implements for_each_mem_pfn_range()
which replaces work_with_active_regions(). All the current users of
work_with_active_regions() are converted.
This simplifies walking over early_node_map and will allow converting
internal logics in page_alloc to use iterator instead of walking
early_node_map directly, which in turn will enable moving node
information to memblock.
powerpc change is only compile tested.
