ia64: remove custom __early_pfn_to_nid()
The ia64 implementation of __early_pfn_to_nid() essentially relies on the
same data as the generic implementation.
The correspondence between memory ranges and nodes is set in memblock
during early memory initialization in register_active_ranges() function.
The initialization of sparsemem that requires early_pfn_to_nid() happens
later and it can use the memblock information like the other architectures.
