b587a409a3 tilelink2 Node: make it possible for {Identity,Output,Input}Node to pass a Vec 
In order to implement a pass-through RAM Monitor model, we will want to support
a variable number of inputs and outputs with BOTH different manager and client
parameters on each bundle.

9bfd8c1cf5 TL2 WidthWidget (#258) 
* tilelink2 Narrower: support widenening and narrowing on all channels

Be extra careful with the mask transformations

We need to make sure that narrowing or widening do not cause a loss
of information about the operation. The addr_hi+(mask|addr_lo) conversions
are now 1-1, except on D, which should not matter.

* tilelink2 SRAM: work around firrtl SeqMem bug

* tilelink2 WidthWidget: renamed from Narrower (it now converts both ways)

* tilelink2 mask: fix an issue with width=1 data buses

e35e7b2ee3 Fix routing in non-contiguous MMIO regions 
This is a temporary fix, which can generate more hardware than necessary, but this is OK for now, since this code will soon be replaced with tilelink2 code.

a7f47f3c23 Reduce default BTB size 
The old value 62 seems to have been a typo introduced over 2 years ago
in commit 63bd0b9d2a.  The intent was to
fit the dhrystone working set (rofl) which the new value of 40 does.
