The streamers demo was using very old top. With the updated of resets,
etc, it stopped working (at least the testbench did stop). So, I finally
updated this top to work (in the testbench at least) with the new BSP.
This required a major re-do of the top. I left from the old as much
as I could. The new top is based on the spec_ref_design. This was
tested only for simulation
(testbech/wr_streamers/streamers-on-spec_trigger-distribution).
A commit with updates to simulation follows.
