Changes to build with a 512-bit main data bus (with all other busses
...
still 64-bits).
Also, the top-level SoC_Top exposes a 64-bit bus still, so hopefully the
GFE configuration is unchanged.
This passes the isa_tests.

That is, don't push in Decode, push from the training structure coming

Enable tracing of physical addresses for RVFI (if PADDR_RVFI is
...
defined).
This is done by adding a vector of padder lookup interfaces to the load
store queue.
This should help with targeted memory translation debugging, and also
with compatability with the current Sail RVFI implemenation which is
probably incorrect with respect to the RVFI spec which calls for virtual
addresses in the maddr field.
