[PATCH v2 0/4] sh: remove unused SLOW_DOWN_IO

[Bjorn Helgaas]

Only alpha and sh define SLOW_DOWN_IO, and there are no uses of it.  Remove
it from sh and clean up some nearby macros.

Changes from v1 to v2:
  - Drop the ia64 patch because Andrew applied it
      https://lore.kernel.org/all/20221021045245.99636C433C1@xxxxxxxxxxxxxxx/

  - Fix the sh build issues reported by the kernel test robot:
      https://lore.kernel.org/all/202210181211.ItV2YuJI-lkp@xxxxxxxxx/

  - Add minor sh cleanup patches to __BUILD_IOPORT_SINGLE(),
    __BUILD_IOPORT_PFX(), and __BUILD_MEMORY_STRING()

  - Split sh and alpha to separate series
