This introduces the part start and part size sub-commands. The purpose of these
is to store the start block and size of a partition in a variable, given the
device and partition number.
This allows reading raw data that fits a single partition more easily.
For instance, this could be used to figure out the start block and size of a
kernel partition when a partition table is present, given the partition number.

Add an optional third argument to the "part list" command which puts a
space seperated list of valid partitions into the given environment
variable. This is useful for allowing boot scripts to iterate of all
partitions of a device.

Since most commands are not public, make them static. This
prevents warnings that no common prototype is available.

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

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} ...
