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

From: Arnd Bergmann
Date: Wed Aug 02 2023 - 14:49:25 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

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.
