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.
