cddfdf0929 Add CHISEL_VERSION make argument 
This allows users to specify if they want to build RocketChip against
Chisel 2 or 3.  Since Chisel 3 is now open source we can add these
submodule pointers directly to avoid a fork of upstream.

7c0c48fac4 Resurrect the backup memory port 
We need this to work for our chip, and it's not been tested in a long
time in upstream -- it didn't even used to build since the Nasti
conversion.  This makes a few changes:

 * Rather than calling the backup memory port parameters MEM_*, it calls
   them MIF_* (to match the MIT* paramater objects).  A new name was
   necessary because the Nasti stuff is now dumped as MEM_*, which has
   similar names but incompatible values.

 * p(MIFDataBits) was changed back to 128, as otherwise the backup
   memory port doesn't work (it only send half a TileLink transaction).
   64 also causes readmemh to bail out, but changing the elf2hex parameters
   works around that.

 * A configuration was added that enabled the backup memory port in the
   tester.  While this is kind of an awkward way to do it, I want to
   make sure I can start testing this regularly and this makes it easy to
   integrate.

db9de94588 Generate and use SCR address header files 
This uses the new SCRFile changes to generate a header file containing a list
of all the SCRs in a core to remove the magic constant "63" (the HTIF clock
divider control register) and replace it with a generated number (which is
still 63).

d3ccec1044 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.
