ed4224dde4 tilelink2 AtomicAutomata: fix AccessAck on same cycle as PutFull 
If we send out the PutFull portion of an AMO, the slave is allowed
to respond with AccessAck on the same cycle. In this case, we are
still in the AMO state, but must still match the D response.

a82cfb8306 tilelink2: replace addr_hi with address (#397) 
When faced with ambiguous routing of wmask=0, we decided to include
