powerpc/64s: Remove SAO feature from Power9 DD1
[ Upstream commit ca80d5d0a8175c9be04cfbce24180b8f5e0a744b ]
Power9 DD1 does not implement SAO. Although it's not widely used, its presence
or absence is visible to user space via arch_validate_prot() so it's moderately
important that we get the value right.
