[PATCH v4] kbuild: buildtar: add dtbs support

[Domenico Andreoli]

From: Domenico Andreoli <domenico.andreoli@xxxxxxxxx>

Make 'make tar-pkg' install dtbs.

v4:
 - Install the dtbs before modules & kernel, not after
 - Check for the dtbs_install target before attempting to invoke it

v3:
 - Check for CONFIG_OF_EARLY_FLATTREE=y instead of ARCH before installing dtbs

v2:
 - Add the kernel release to the destination path
