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