linux: add binary devicetree generation
* Add binary devicetree generation support * Taken from OE * v2 reorder patch set * v3 remove package_stagefile_shell * v4 rename devicetree_image function to install_append * remove pkg_postinst_kernel-devicetree, pkg_postrm_kernel-devicetree functions * Update KERNEL_DEVICETREE_FLAGS use "-p" option instead of "-S" which is deprecated Signed-off-by: Adrian Alonso <aalonso00@gmail.com> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
