[PATCH v5 03/20] target/arm: ensure HVF traps set appropriate MemTxAttrs |

As most HVF devices are done purely in software we need to make sure
we properly encode the source CPU in MemTxAttrs. This will allow the
device emulations to use those attributes rather than relying on
current_cpu (although current_cpu will still be correct in this case).
