Request for testing: [PATCH] remove SPR short-hand defines

All,

Can you please take a whirl at testing this patch.  I think I got all the cases in which we used SPR short-hand defines and replaced them with SPRN_<FOO> for ppc32.

Let me know if you have any issues (I've done simple build tests on 4xx, 8xx, 82xx, 85xx, and pmac)

Thanks
