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

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.

 environment loaded from the file's location in the directory tree.
