[PATCH v5 11/11] fdt: Treat device tree file type like ACPI

[Alexander Graf]

We now have signature check logic in grub which allows us to treat
files differently depending on their file type.

Treat a loaded device tree like an overlayed ACPI table.
Both describe hardware, so I suppose their threat level is the same.
