    Pull generic ioremap support from Christoph Hellwig:
     "This adds the remaining bits for an entirely generic ioremap and
      iounmap to lib/ioremap.c. To facilitate that, it cleans up the giant
      mess of weird ioremap variants we had with no users outside the arch
      code.
    
      For now just the three newest ports use the code, but there is more
      than a handful others that can be converted without too much work.
    
      Summary:
    
       - clean up various obsolete ioremap and iounmap variants
    
       - add a new generic ioremap implementation and switch csky, nds32 and
         riscv over to it"
