b1719cfee0 Fixing requirements for PAddrBits (#961) 
Previously, the requirement for PAddrBits only checked to be equal or greater than the bundle bits. Changing it to check for these to match exactly as for cases when the PAddrBits greater than address bits we could run into scenarios which cause possible address wrap around issues.

e140893a01 Use 1-entry queue on processor-side E-channel

eadf4e9fcc Revert "tile: add option for tile boundary buffers" 
This reverts commit b64b87ad07.

The crossings already have buffering in those places where it was
appropriate. Adding more does not help flow through paths.

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
