[U-Boot] [PATCH 10/27] sparc: Use asm-generic/io.h

Convert the sparc architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As the generic implementations are
suitable for sparc this is primarily a matter of moving code.
Feedback from architecture maintainers is welcome.
