x86, memblock: Add get_free_all_memory_range()

Browse source

get_free_all_memory_range is for CONFIG_NO_BOOTMEM=y, and will be called by
free_all_memory_core_early().

It will use early_node_map aka active ranges subtract memblock.reserved to
get all free range, and those ranges will convert to slab pages.

-v4: increase range size
