[PATCH 2/2, variant B] ARM: move mmiocpy/mmioset exports to io.c

[Arnd Bergmann]

The prototypes for mmioset/mmiocpy are intentionally hidden
inside of inline functions, which breaks the EXPORT_SYMBOL
statements when symbol versioning is enabled.

This moves the two exports from the files that implement the
code into the kernel/io.c file, adding another local declaration
there.
