MIPS: Loongson64: Clean up numa.c
(1) Replace nid_to_addroffset() with nid_to_addrbase() and then remove the
related useless code.
(2) Since end_pfn = start_pfn + node_psize, use "node_psize" instead of
"end_pfn - start_pfn" to avoid the redundant calculation.
(3) After commit 6fbde6b492df ("MIPS: Loongson64: Move files to the
top-level directory"), CONFIG_ZONE_DMA32 is always set for Loongson64
due to MACH_LOONGSON64 selects ZONE_DMA32, so no need to use ifdef any
more, just remove it.
