I afraid it will make arch/ppc unhappy - these got included to both.
And the headers required because there used to be same asm/io.h where this stuff used to reside, and from 
the recent time, arch/powerpc has separate io.h that made all the CPM2-related kinda hosed.

As a good thing, this header is only for the time we'll have to have same target working both in ppc and powerpc.
I think this can be revisited after the patch about cleaning-up CPM_MAP_ADDR from the drivers and core code.
