powerpc64: Stop assuming new processors have VSX tuliom/microwatt
VSX has been available on IBM POWER since POWER7. All IBM processors compliant with POWER ISAs 2.07, 3.0 and 3.1 also support VSX. This patch aims to remove a barrier for new processors as they start to support Linux on powerpc64 while not having support for all the altivec and vsx instructions.
