reconf: bind a config port of the xicu to the internal dspin_routers

  • This config port is bound to the blackhole_pos port of the dspin_router. This way, the software can configure the dspin_router by writing in the first configuration register of the xicu.
  • The same xicu's config port is connected to the 5 local routers of the internal interconnect. Therefore, the 5 routers share the same configuration.
