reconf: introducing a softs directory in the reconfiguration branch

  • This softs directory contains a minimalistic (giet-like) library of drivers and some utility functions.
  • Introducing a simple unit test in the vci_cc_vcache_wrapper component to test the newly introduced watchdog timer mechanism. This unit test uses the minimalistic library.
