Adding firmware output of firmware information when ndctl list -D -F is used.
Components displayed are current firmware version, updated firmware version,
and if a coldboot is required (firmware updated).

v2:
- Added copyright
- Added support for human readable option (hex) for versions
- Removed check against CMD_CALL as it's not useful
