Don't route PLIC interrupts through PRCI
...
The PLIC is local to the Coreplex, and PRCI should not be.

First cut at refactoring unittests into a top-level utility. Individual tests co-located with their DUT. No functional changes.

Add option to execute JAL from decode stage
...
This is particularly helpful for designs that don't have a BTB, but
it becomes the critical path for designs with RVC. Caveat emptor.

Disable Mul early out by default if XLen == 32
...
With a default unroll of 8, it doesn't help performance, but costs area.

now able to add periphery devices through traits
...
Unfortunately, I had to touch a lot of code, which weren't quite possible to split up into multiple commits.
This commit gets rid of the "extra" infrastructure to add periphery devices into Top.

Make DefaultRV32Config be RV32IMAFCS, not RV32IMC

The latter is more the domain of TinyConfig.

Add support for L1 data scratchpads instead of caches
...
They fit in the same part of the address space as DRAM would be, and
are coherent (because they are not cacheable).
They are currently limited to single cores without DRAM. We intend
to lift both restrictions, probably when we add support for
heterogeneous tiles.

Add TileId parameter, generalizing GroundTestId
...
This usually shouldn't be used in Tiles that are meant to be P&R'd once
and multiply instantiated, as their RTL would no longer be homogeneous.
However, it is useful for conditionalizing RTL generation for
heterogeneous tiles.

Closes #228 .
In commit 3f8c60bbd6dd4e91b2e4c4e11fbabff8708b66ff I inadvertently
changed the configuration while refactoring it.
