Massive update containing several months of changes from the now-defunct private chip repo.
...
* Adds support for a L2 cache with directory bits for tracking L1 coherence (DefaultL2Config), and new metadata-based coherence API.
* Additional tests.
* New virtual memory implementation, priviliged architecture (1.7), custom CSRs, FDivSqrt unit
* Updated TileLink protocol, NASTI protocol SHIMs.
* Lays groundwork for multiple top-level memory channels, superscalar fetch.
* Bump all submodules.

Fix fpga_mem_gen for Python 2 and 3 Environments
...
Two quick fixes that enable fpga_mem_gen to work with either Python 2 or
Python 3:
* Change an `xrange` instance to `range`
* Wrap the arguments of a bare `print` in parentheses

Fix data array reset bug
...
io.resp.valid could have been valid the cycle after reset, causing the
write mask in the acquire tracker to have an erroneous value after reset.
This caused the L1 I$ to be refilled with the wrong data.
This probably only affects programs loaded with +loadmem and so shouldn't
matter for the EOS24 silicon. It should only affect the first L2 xact,
which, in practice, would be an HTIF write to load the program.

Avoid spurious D$ assertion failures
...
For the Rocket pipeline, this fix is needless and the problem is that the
assertion is too conservative, but I solved it this way to avoid problems
for other plausible use cases where physical and virtual accesses are
intermixed.
