[POWERPC] Copy over headers from arch/ppc to arch/powerpc that we need
To build arch/powerpc without including asm-ppc/ we need these files
in asm-powerpc/
Moved some headers under arch/powerpc/platforms if they were only used by
platform or driver files and fixed up the source file includes to match
the new locations
