The compiled device tree database file needs to be put into a section
named .dtb. This patch also is in-line with the proposed extension
of the UKI spec to explicitly allow multiple DTB sections.

Please note, that I could not test this patch with multiple device
trees due to lack of a suitable board. For a single device tree it
indeed works properly.

Best regards,
Felix Moessbauer
