ppc/hash64: Rework R and C bit updates
With MT-TCG, we are now running translation in a racy way, thus
we need to mimic hardware when it comes to updating the R and
C bits, by doing byte stores.
The current "store_hpte" abstraction is ill suited for this, we
replace it with two separate callbacks for setting R and C.
