f83d1d0aaf coreplex: rename trait CoreplexRISCVPlatform 
This makes it clear we are talking about the devices one expects in the
platform, not the ISA.

aabd17d935 rocketchip: must create bundles within Module scope 
1. Bundles be created after base class Module constructor runs
2. Bundles must be created before Module(...) runs

Solution: pass a bundle constructor to the cake base class

Require the constructor to take a parameter so people don't use it by
accident; they should get a type error.

Consistently name all the cake arguments with an _io, _coreplex, _outer,
so that they don't shadow the base class variables you should be using.

968851f7e3 Default to configurable priorities 
up-to-7 levels is kind of arbitrary, but I'm unwilling to introduce
a new Parameter at the moment.

9910c69c67 Move a bunch more things into util package 
A lot of utility code was just being imported willy-nilly from one
package to another. This moves the common code into util to make things
more sensible. The code moved were

 * The AsyncQueue and AsyncDecoupledCrossing from junctions.
 * All of the code in rocket's util.scala
 * The BlackBox asynchronous reset registers from uncore.tilelink2
 * The implicit definitions from uncore.util

e928b741ce Default mtvec=0, not None 
Setting it to None was a mistake.  It makes it far harder to
diagnose boot bugs, as you end up fetching from random addreses
after trapping.

c45cc76cef Get rid of remaining MemIO code 
The only thing we were still using it for was for the MIFDataBits
and MIFTagBits parameters. We replace these with EdgeDataBits and
EdgeIDBits.
