powerpc/64s: Remove SAO feature from Power9 DD1

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.

Fixes: 7dccfbc3 ("powerpc/book3s: Add a cpu table entry for different POWER9 revs")
