Wesley W. Terpstra 9804bdc34e tilelink: remove obsolete addr_lo signal (#895) 
When we first implemented TL, we thought this was helpful, because
it made WidthWidgets stateless in all cases. However, it put too
much burden on all other masters and slaves, none of which benefitted
from this signal. Furthermore, even with addr_lo, WidthWidgets were
information lossy because when they widen, they have no information
about what to fill in the new high bits of addr_lo.

Henry Cook 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
