bff0ffa428 tilelink2 RegisterRouter: fix output data glitches 
If a device changes a register while it's being read but not yet accepted,
this an lead to 'data' changing while 'valid' is high. A violation. The
problem is that RegMapper is fundamentally DecoupledIO. So fix it with a
Queue.

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

69e121260e [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.

357d06ac9c 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.

d9e209365d 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.
