reconf: add test for the recovery routing function on the dspin_router

  • The test performs a reconfiguration of a cycle-free contour around a blackhole in a 3x3 platform. The blackhole (faulty routers) is in the cluster (1,1).
  • Introduce a reconf:xicu driver in the softs directory. For now this driver contains only a getter/setter for the configuration registers in the reconf:vci_xicu.
