[PATCH] ppc32: Kill PVR_440* defines 

The following patch changes the usages of PVR_440* into strcmp's with the
cpu_name field, and removes the defines altogether.  The Ebony portion was
briefly tested long ago.  One benefit of moving from PVR-tests to string
tests in general is that not all CPUs can be on and be able to do this type
of comparison.

See http://patchwork.ozlabs.org/linuxppc/patch?id=1250

 for the original
thread.
