92668d68c1 cmd_part: don't print cmd name twice in help
The core implementation of "help" already prints the command name before
the help text of a specific command. Remove it from part's own help text
to avoid it being printed twice:

Tegra114 (Dalmore) # help part
part - disk partition related commands

Usage:
part part uuid <interface> <dev>:<part>
    - print partition UUID
...

5cf41dccff cmd_part: add partition-related command
This implements the following:

part uuid mmc 0:1
  -> print partition UUID
part uuid mmc 0:1 uuid
  -> set environment variable to partition UUID
part list mmc 0
  -> list the partitions on the specified device

"part uuid" can be useful when writing a bootcmd which searches all
known devices for something bootable, and then wants the kernel to
use the same partition as the root device, e.g.:

part uuid ${devtype} ${devnum}:${rootpart} uuid
setenv bootargs root=PARTUUID=${uuid} ...
