powerpc: Enforce usage of R0-R31 where possible
Enforce the use of R0-R31 in macros where possible now we have all the fixes in. R0-R31 macros are removed here so that can't be used anymore. They should not be defined anywhere. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
