iop: genconfig_wrap: Deprecate --clean option
- deprecate -c /--clean option Clean for gen_config.py does something else than original
- few script improvements
- fix previous approach with calling gen_config.py with quoted arguments:
${target_script} "${args[@]}"
This resulted in a call:/scripts/gen_config.py 'sw40j eval analytics'
treated by gen_conf.py as a single argument.
