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

[tilelink2] Add unit tests for many TL2 components

These tests mostly use the Fuzzer and RAMModel to check that adapters
correctly handle randomly generated legal traffic.

tilelink2 WidthWidget: Gets must have their mask adjusted ( #353 )
...
The mask of a Get should also be converted.
This manifested as a bug when going from 32=>64 bits. A large Get
could end up with mask that was not full.

Tl2 addr width0 ( #346 )
...
* tilelink2 Edges: add accessor methods for address and addr_{hi,lo}
* tilelink2: use addr_lo instead of relying on truncation
Truncation can mess up if the width should be 0, but IS 1.
