Recently added Power10 prefixed VSX instruction are included
unconditionally in the kernel. If they are executed on a
machine without VSX support, it might create issues. Fix that.
Also fix one mnemonics spelling mistake in comment.
Fixes: 50b80a12e4cc ("powerpc sstep: Add support for prefixed load/stores")
