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.
