powerpc: clean up after powermac build merge
Complete moving arch/ppc64/kernel/mpic.h, include/asm-ppc/reg.h, include/asm-ppc64/kdebug.h and include/asm-ppc64/kprobes.h Add arch/powerpc/platforms/Makefile and use it from arch/powerpc/Makefile Introduce OLDARCH temporarily so we can point back to the originating architecture Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
