b772edcb1b Allow hit-under-MMIO and multiple MMIOs in blocking D$ 
The latter feature is by default disabled, since there aren't enough
ID bits.

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.

18e7ea89f2 Get rid of broken groundtests 
The NastiConverterTest, PCIeMockupTest, and DirectGroundtest
configurations have been broken by recent changes.

The NastiConverterTest has been superseded by a unit test and the
other two were only created for an attempt at FPGA debugging.
They weren't actually very useful for that purpose, so might as well get
rid of them.

c77c244016 Get rid of NASTI memory interconnects 
These were made for a previous Hurricane tapeout, but we are now doing
all of the memory routing in TileLink, so they are no longer needed.

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.
