656609d610 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.

68064ba260 systembus: don't double down on buffers 
The order should be:
  master => buffer|xing => fifofixer => splitter => xbar

2e4f1611ed tilelink: Error device supports Acquire 
We need this if we want to divert traffic to it from a TL-C slave.

01ca3efc2b 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
