[U-Boot] [PATCH 06/27] microblaze: Use asm-generic/io.h

[Paul Burton]

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

Feedback from architecture maintainers is welcome.
