Hi,

These patches simplify several uses of memblock iterators and hide some of
the memblock implementation details from the rest of the system.

The patches are on top of v5.8-rc7 + cherry-pick of "mm/sparse: cleanup the
code surrounding memory_present()" [1] from mmotm tree.

v2 changes:
* replace for_each_memblock() with two versions, one for memblock.memory
  and another one for memblock.reserved
* fix overzealous cleanup of powerpc fadamp: keep the traversal over the
  memblocks, but use better suited iterators
* don't remove traversal over memblock.reserved in x86 numa cleanup but
  replace for_each_memblock() with new for_each_reserved_mem_region()
* simplify ramdisk and crash kernel allocations on x86
* drop more redundant and unused code: __next_reserved_mem_region() and
  memblock_mem_size()
* add description of numa initialization fix on arm64 (thanks Jonathan)
* add Acked and Reviewed tags
