[PATCH 4/4] sh: machvec: remove custom ioport_{un,}map()

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

These functions were only used on the microdev
board that is now gone, so remove them to simplify
the ioport handling.

This could be further simplified to use the generic
I/O port accessors now.
