This patchset tries to remove ioremap_uc() in the current architectures
except of x86 and ia64. They will use the default ioremap_uc definition
in <asm-generic/io.h> which returns NULL.

If any arch sees a breakage caused by the default ioremap_uc(), it can
provide a sepcific one for its own usage.

v1->v2:
- Update log of patch 2, and document related to ioremap_uc()
according to Geert's comment.
- Add Geert's Acked-by.

mips: add <asm-generic/io.h> including
