Geert Uytterhoeven 781c4d6f5f m68k/io: Switch mmu variant to <asm-generic/io.h> ...

The dummy functions defined in <asm/io_mm.h> can be provided by
<asm-generic/io.h>.

As nommu already uses <asm-generic/io.h>, move its inclusion to
<asm/io.h>, and add/adjust include guards where appropriate.

This gets rid of lots of "statement with no effect" and "unused
variable" warnings when compile-testing.
