[meta-ti,master/scarthgap,v2,2/2] meta-ti-bsp: Add KERNEL_DEVICETREE_PREFIX logic to Poky images

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.

v2: Changed guard variable from poky to ti-soc and renamed .inc file.

So will we need to do this for all images then, even custom ones? Seems messy,
is there no way we can bubble up this KERNEL_DEVICETREE_PREFIX support into
a more core layer. It seems like something that would be useful beyond just TI.

Maybe we could find a way with a custom kernel-devicetree.bbclass in our layer
until then also.
