[POWERPC] Schedule removal of arch/ppc

The arch/ppc tree has been in a semi-nebulous "bug fix only" state for a
few kernel releases now.  The patch below officially declares this as of
the 2.6.22 kernel release and schedules arch/ppc for removal in June of
2008.

+What: The arch/ppc and include/asm-ppc directories
+When: Jun 2008
+Why:  The arch/powerpc tree is the merged architecture for ppc32 and ppc64
+      platforms.  Currently there are efforts underway to port the remaining
+      arch/ppc platforms to the merged tree.  New submissions to the arch/ppc
+      tree have been frozen with the 2.6.22 kernel release and that tree will
+      remain in bug-fix only mode until its scheduled removal.  Platforms
+      that are not ported by June 2008 will be removed due to the lack of an
+      interested maintainer.
