Added missing file...
> nvmectl(8): sync with FreeBSD HEAD r316105.
>
> - Expand the SMART / Health Information Log Page (Page 02) printout based on
> NVM Express 1.2.1 Standard.
> - Implement Intel-specific log pages.
> - Implement HGST-specific log pages.
> - Implement wdc-specific nvme control options.
> - Add the ability to dump log pages directly in binary to stdout.
