powerpc: Add 2.06 tlbie mnemonics
This adds the PowerPC 2.06 tlbie mnemonics and keeps backwards compatibilty for CPUs before 2.06. Only useful for bare metal systems. Signed-off-by: Milton Miller <miltonm@bga.com> Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
