6f3ff634f2 DTS: collect common DTS nodes and move timebase-frequency to cores 
Putting the common DTS nodes into a shared object makes them get
emitted only one time. Plus it's better style.

timebase-frequency should really have been in the cpu nodes in the
first place according to the spec anyway. I was foolishly trying to
save bytes. However, now we really want it there in case it differs.

3b299397db diplomacy: bind resources to outer-most binding 
This is probably the wrong thing to do, but it is expedient for now.
We need a better way to do cross-coreplex visibility.

e894d64bca diplomacy: support := composition 
This makes it possible to treat chained composition associatively.
x := y :=? z :=* a ...

It also makes it easy to chain multiple optional adapters:
node :=? (Seq(a, b) ++ c ++ d)

fef5054cec diplomacy: disambiguate names only when necessary 
If two (or more) 'auto_' things have the same name, append _0 and _1 to them.

The order of definitions is unaffected; ie:
  a => a_0
  b => b_0
  b => b_1
  c => c
  a => a_1

bc225a4e82 diplomacy: place Monitors inside LazyModules sinks 
We used to place Monitors at the point of the ':='.
This was problematic because the clock domain might be wrong.
Thus, we needed to shove Monitors a lot.

Furthermore, now that we have cross-module ':=', you might not even
have access to the wires at the point where ':=' is invoked.
