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

[Bjorn Helgaas <helgaas@kernel.org>]

From: Bjorn Helgaas <bhelgaas@google.com>

[Sorry for the noise; I sent this a few minutes ago, but it bounced from
all the individual recipients because of DMARC issues]

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@smtp.kernel.org/

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

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

  - Split sh and alpha to separate series

Bjorn Helgaas (4):
  sh: remove unused SLOW_DOWN_IO
  sh: remove unused __BUILD_IOPORT_SINGLE 'pfx' parameter
  sh: remove unnecessary __BUILD_IOPORT_PFX()
  sh: remove unnecessary __BUILD_MEMORY_STRING() 'pfx' parameter
