meta-ti-bsp: Add KERNEL_DEVICETREE_PREFIX logic to Poky imagesscarthgap-wip

The boot partition for things like the wic image, use the
KERNEL_DEVICETREE to populate DTBs.  But for the meta-ti-bsp kernels we
tend to rely on the KERNEL_DEVICETREE_PREFIX to glob pull in DTBs
instead of a single list.  So using dynamic layers, we can inject the
proper code to properly resolve the KERNEL_DEVICETREE in each image
file.
