[PATCH] Create include/asm-powerpc

The ppc and ppc64 trees are hopefully going to merge over time, so this
patch begins the process by creating a place for the merging of the
header files.

Create include/asm-powerpc (and move linkage.h into it from
asm-{ppc,ppc64} since we don't like empty directories).  Modify the
ppc and ppc64 Makefiles to cope.
