sbus => pbus: 2 buffers should already be enough
...
There is a buffer on the sbus backside.
There is a buffer on the pbus frontside.
Between them is only an AtomicAutomata.
That should be enough for most designs.

SystemBus: add stupidly many (4 more) buffers from sbus=>pbus
...
This should probably be reverted.

SystemBus: split FIFOFixers along bus boundaries
...
If you have a system with a lot of periphery slaves, you wan to FIFO fix
them on the periphery bus rather than paying the circuit cost at the sbus.

These functions were actually for cross connecting chips.

systembus: don't double down on buffers
...
The order should be:
master => buffer|xing => fifofixer => splitter => xbar

tilelink: Error device supports Acquire

We need this if we want to divert traffic to it from a TL-C slave.

Combine Coreplex and System Module Hierarchies ( #875 )
...
* coreplex collapse: peripherals now in coreplex
* coreplex: better factoring of TLBusWrapper attachement points
* diplomacy: allow monitorless :*= and :=*
* rocket: don't connect monitors to tile tim slave ports
* rename chip package to system
* coreplex: only sbus has a splitter
* TLFragmenter: Continuing my spot battles on requires without explanatory strings
* pbus: toFixedWidthSingleBeatSlave
* tilelink: more verbose requires
* use the new system package for regression
* sbus: add more explicit FIFO attachment points
* delete leftover top-level utils
* cleanup ResetVector and RTC
