568bfa6c50 Purge legacy HTIF things 
The SCR file is gone, too, because it was tightly coupled.  The
general concept could be revived as a module that somehow connects
to the debug module.

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.

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).

a42832fc70 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
