ppc/spapr|pnv: Remove SAO from pa-features
SAO is a page table attribute that strengthens the memory ordering of
accesses. QEMU with MTTCG does not implement this, so clear it in
ibm,pa-features. This is an obscure feature that has been removed from
POWER10 ISA v3.1, there isn't much concern with removing it.
