arm: Use asm-generic/io.h
Convert the arm architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As the generic implementations are
suitable for arm this is primarily a matter of removing code.
This has only been build-tested, feedback from architecture maintainers
is welcome.
