In practice the difference is meaningless as the only portable driver that uses ioremap_uc is atyfb which probably doesn't show up on nommu devices.

Remove these definitions and rely on asm-generic/io.h instead. For this to work the backup ioremap_* defintions needs to be changed to purely cpp macros instea of inlines to cover for architectures like openrisc that only define ioremap after including .
