Revert "x86/e820: put !E820_TYPE_RAM regions into memblock.reserved"
commit 124049decbb1 ("x86/e820: put !E820_TYPE_RAM regions into
memblock.reserved") breaks movable_node kernel option because it changed
the memory gap range to reserved memblock. So, the node is marked as
Normal zone even if the SRAT has Hot pluggable affinity.

The original issue is fixed by the former patches, so let's revert commit
124049decbb1 ("x86/e820: put !E820_TYPE_RAM regions into
memblock.reserved").
