memblock: Separate out memblock_find_in_range_node()
Node affine memblock allocation logic is currently implemented across
memblock_alloc_nid() and memblock_alloc_nid_region(). This
reorganizes it such that it resembles that of non-NUMA allocation API.
Area finding is collected and moved into new exported function
memblock_find_in_range_node() which is symmetrical to non-NUMA
counterpart - it handles @start/@end and understands ANYWHERE and
ACCESSIBLE. memblock_alloc_nid() now simply calls
memblock_find_in_range_node() and reserves the returned area.
This makes memblock_alloc[_try]_nid() observe ACCESSIBLE limit on node
affine allocations too (again, this doesn't make any difference for
the current sole user - sparc64).
