[U-Boot] [PATCH v2 04/13] m68k: Use asm-generic/io.h

[Paul Burton]

Convert the m68k architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As the generic implementations are
suitable for m68k this is primarily a matter of emoving code.

Feedback from architecture maintainers is welcome.
