configs: Do not require default options for caches
This change is useful when using custom simulation scripts that do not
rely on configs/common/Options.py.
Without this change, the custom script always needed to provide some
value for cache sizes and HW prefetchers configuration; with this change
it is possible to provide no value and use what is defined in the core
configuration as default.
