powerpc64: Stop assuming new processors have VSXtuliom/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.
