classes/image_types_ostree.bbclass: add device tree to boot/devicetree-*

Include device trees into boot/devicetree-*-checksum. Device trees with
this name format get picked up by ostree and copied into boot/.
Ostree also generates entry inside uEnv.txt called fdt_file pointing to
this device tree.

Normaly one would include only one device tree. If KERNEL_DEVICETREE
includes more then one device tree this will add all the device trees
but ostree will still pick only one device tree and include it into
boot.

We are working on modifications to ostree so it will pickup all
the device trees.
