This allows us to distinguish not only by platform and subtype at build
time, but also by device-specific model.
It is required because two devices may share the same kernel sources and
thus build the same dtbs, but the resulting dt.img should be devie
specific and only contain the specific dtbs for that device.
Otherwise we are likely to violate dt.img size constraints by including
too many dtbs (which is the case for a5y17lte and a7y17lte right now).
For now, the feature will be optional (existing samsung_dtbh.h headers
don't have to be changed) but that might change in the future.

Factor out DT image creation code into a small host
library.
Create a new host binary which allows us to create
device tree blob (DTB) images.
