mm: remove early_pfn_in_nid() and CONFIG_NODES_SPAN_OTHER_NODES
The memmap_init() function was made to iterate over memblock regions and as the result the early_pfn_in_nid() function became obsolete. Since CONFIG_NODES_SPAN_OTHER_NODES is only used to pick a stub or a real implementation of early_pfn_in_nid(), it is also not needed anymore. Remove both early_pfn_in_nid() and the CONFIG_NODES_SPAN_OTHER_NODES.
