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.

rocketchip: must create bundles within Module scope
...
1. Bundles be created after base class Module constructor runs
2. Bundles must be created before Module(...) runs
Solution: pass a bundle constructor to the cake base class
Require the constructor to take a parameter so people don't use it by
accident; they should get a type error.
Consistently name all the cake arguments with an _io, _coreplex, _outer,
so that they don't shadow the base class variables you should be using.

Fix PutBlock after Release bug
...
There is logic in the broadcast hub to skip the outer acquire if there
is an outgoing release, since the data will be written out through the
release channel. However, this will cause an issue in the case of
PutBlock requests. If the tail beats of the PutBlock show up after the
outer release has already been sent, the data will be corrupted.
The fix is to make the outer release block if there are pending
inner PutBlock beats.
