Benjamin Herrenschmidt 3054b0ca4b target/ppc: Fix ordering of hash MMU accesses 
With mttcg, we can have MMU lookups happening at the same time
as the guest modifying the page tables.

Since the HPTEs of the hash table MMU contains two words (or
double worlds on 64-bit), we need to make sure we read them
in the right order, with the correct memory barrier.

Additionally, when using emulated SPAPR mode, the hypercalls
writing to the hash table must also perform the udpates in
the right order.

Note: This part is still not entirely correct
