[ptxdist] [PATCH v2 1/3] kernel: add make target for the installed device trees

[ptxdist] [PATCH v2 1/3] kernel: add make target for the installed device trees

[Roland Hieber]

This makes it easy to depend on the kernel.targetinstall stage by
depending on one of the .dtb's that it installs into the image dir, e.g.
when building a custom recipe for a FIT image. As a nice side-effect,
you can simply call "ptxdist image <board.dtb>" to build the device
tree.

Nobody ever replaces those comments with something useful.
Just select the regular kernel here so we have a working default.

No dependencies here. This should be covered by selecting the relevant
packages.

Ask for the two while building the template. Maybe with a useful default?

Add the same thing to the kernel template to make sure that behaves the
same way. Sorry, forgot about that when I reviewed the first version.
