[PATCH] Documentation: barebox environment: recommend a partition type GUID for GPT partitions

[Marco Felsch <m.felsch@pengutronix.de>]

The partition type GUID was generated randomly. Having a defined GUID
should reduce the risk of collisions in the future.

The GUID and a phandle reference to the storage medium could be used as
replacement for device-path if the medium supports GPT.

 The file-path is the name of a file located in a FAT filesystem on the
 device named in device-path.  This filesystem will be mounted and the
 environment loaded from the file's location in the directory tree.
