[U-Boot] Add a new command to U-Boot

[Subodh Nijsure <sunijsur@cisco.com>]

Have you looked at code in common/cmd_date.c?

If you see at the end of the file there is macro U_BOOT_CMD() that adds the
command date, there is function do_date that is invoked, so if you wanted to
implement your own version of date command you will have to implement your
own do_date function.
