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} ...
