nds32: use generic ioremap
Use the generic ioremap_prot and iounmap helpers. Note that the io.h include in pgtable.h had to be removed to not create an include loop. As far as I can tell there was no need for it to start with. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Greentime Hu <green.hu@gmail.com>
