Merge tag 'ioremap-5.5' of git://git.infradead.org/users/hch/ioremap

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"
