[meta-xilinx] Using devicetree from devicetree.bbclass with fitimage?

[Philip Balister]

Subject pretty much says it all :)

So the minized uses the devicetree bbclass to build the dtb file. But
the kernel-fitimage class expects the KERNEL_DEVICETREE variable to be set.

How can I use the kernel-fitimage and devicetree bbclasses?
