memblock, x86: Replace memblock_x86_find_in_range_node() with generic memblock calls
With the previous changes, generic NUMA aware memblock API has feature
parity with memblock_x86_find_in_range_node(). There currently are
two users - x86 setup_node_data() and __alloc_memory_core_early() in
nobootmem.c.
This patch converts the former to use memblock_alloc_nid() and the
latter memblock_find_range_in_node(), and kills
memblock_x86_find_in_range_node() and related functions including
find_memory_early_core_early() in page_alloc.c.
