[U-Boot] [PATCH 08/27] openrisc: Use asm-generic/io.h

[Paul Burton]

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

Feedback from architecture maintainers is welcome.
