EDKII Platform Has Device Tree GUID
A NULL protocol instance with this GUID in the DXE protocol database, and/or
a NULL PPI with this GUID in the PPI database, implies that the platform
provides the operating system with a Device Tree-based hardware description.
Note that this is not necessarily exclusive with different kinds of hardware
description (for example, an ACPI-based one). A platform driver and/or PEIM
is supposed to produce a single instance of the protocol and/or PPI (with
NULL contents), if appropriate.
